This research paper presents a study on (Fe) doped CdO nanoparticles focusing on their structural (XRD), thermal (TGA and DTA), optical (UV–vis), magnetic (VSM and ESR), and electrical characteristics. The synthesis of Cd1-xFexO with (x = 0.0, 0.01, 0.05, 0.10, 0.15, and 0.20) nanoparticles was carried out using the co– precipitation technique. Fe dopants showed a great impact on the structural parameters and the thermal stabilities of obtained nanomaterials. SEM and TEM imaging techniques are employed to investigate the morphology, size, and distribution of the Cd1-xFexO nanoparticles. UV spectroscopy was employed to better understand the electronic transitions and optical characteristics. Furthermore, magnetization measurements from ESR and VSM showed a weak ferromagnetic order with a high Fe concentration. For instance, the Ac electrical conductivity measurements were used to determine the electrical properties, dielectric losses, and charge transport mechanisms between the Fe-dopants and CdO. The structural, thermal, optical, magnetic, and electrical characteristics data are complemented to better understand for Cd1-xFexO materials for employing them in magnetic storage and sensors, photocatalysis, other future applications.

In industrial settings, mechanical systems for clamping workpieces onto machine tools or for lifting and handling ferrous material are often replaced by magnetic clamping systems. For large lifting applications, the most suitable magnetic clamping systems are electromagnetic (EM) and electro-permanent (EP) approaches. Their configurations, direct and induced poles or direct poles only, need to be discussed in order to choose the most appropriate and economical setup for the specific application. In addition, an evaluation of the difference in the energy efficiency between EM and EP systems, which is often not simple, is presented. To achieve this, a hybrid control system for EM or EP systems was developed and, with the help of this prototype, an analysis of these two magnetic systems was carried out to highlight the main differences. The hybrid control system consists of a single control unit that can be used by both systems, and can be achieved by simply changing the type of lifting magnet. In this research, the realization, operational description, and analysis performed on this prototype were addressed. [ABSTRACT FROM AUTHOR]

• Physical and magnetic properties of new Ca-Zn based hexaferrites were reported. • Ferrite specimens of Ca 0.5 Zn 0.5 Fe 12-x Cr x O 19 (x = 0.0, 0.5, 1.0, 1.5, and 2.0) were prepared via conventional sol–gel combustion. • The magnetic characteristics of the samples showed a decline in coercivity (Hc) to 1.541 kOe and an increase in saturation magnetization (Ms) to 21.766 emu/g. • The cause of the improvement of saturation magnetization and magnetic remanence and the decrease in the coercivity was determined utilizing pertinent variables, including cation difference, crystallite size, and anisotropy constant. • The samples' low coercivity and exceptional saturation magnetization enhanced their usefulness as filters, oscillators, antennas, interferometric systems, electromagnetic sensors storage devices and recording applications. An assortment of chromium-doped calcium-zinc ferrite specimens with the elemental composition Ca 0.5 Zn 0.5 Fe 12-x Cr x O 19 (x = 0.0–2.0) are synthesized employing the sol–gel scheme. X-ray diffraction data confirm the presence of a sole hexagonal phase of M−type hexaferrites; the lattice variables 'a' and 'c' fluctuate between 5.85 to 5.90 Å and 24.92 to 24.98 Å. Microstructural parameters are explained to gain insights into synthesized material. Morphology suggests the uniform distribution of particles. Magnetic investigations show a drop in coercivity (H c) to 1.541 kOe, an increase in the saturation magnetization (M s) to 21.766 emu/g and remanence (M r) to 13.395 emu/g. Based on relevant characteristics such as cationic difference between Fe and Cr, crystal structure, and anisotropy constant, the cause of the amplification of saturation magnetization, magnetic remanence and the decrease in coercivity are identified. According to the findings, adding chromium to the ferrite materials considerably mellowed them, making them perfect for cutting-edge, high-end recording applications. [ABSTRACT FROM AUTHOR]

The use of metallic nanowires is mostly reduced to scientific areas where a small quantity of nanostructures are needed. In order to broaden the applicability of these nanomaterials, it is necessary to establish novel synthesis protocols that provide a larger amount of nanowires than the conventional laboratory fabrication processes at a more competitive cost. In this work, we propose several modifications to the conventional electrochemical synthesis of nanowires in order to increase the production with considerably reduced production time and cost. To that end, we use a soft anodization procedure of recycled aluminum at room temperature to produce the alumina templates, followed by galvanostatic growth of CoFe nanowires. We studied their morphology, composition and magnetic configuration, and found that their properties are very similar to those obtained by conventional methods.

Highlights • PrCo 3−x Fe x crystallize in rhombohedral PuNi 3 type structure (R-3m) for x < 1. • Co substitution by Fe leads to an increase of Tc and Ms for PrCo 3−x Fe x (x ≤ 0.75). • PrCo 3−x Fe x (x ≤ 0.75) has a decrease in Hc and anisotropy field with Fe content. • Local environment can be differentiated only with distances of 5.2 Å. • EXAFS: Fe atoms preferably occupy the 18h site in PrCo 3−x Fe x (x < 1). Pr 2 Co , Fe 7 (P6/mmm) following a direct structure comparison. • 18 h site in Pr(Co,Fe)3 (R-3m) is equivalent to the 12 k site in Pr 2 Co , Fe 7 (P6/mmm). Abstract Nanocrystalline PrCo 3 - x Fe x (x ⩽ 1) powder samples were synthesized by high energy milling and subsequent annealing at 1023 K for 30 min. The samples crystallize in the PuNi 3 -type structure (space group R 3 ¯ m) for x < 1 , confirmed by means of X-ray diffraction. In order to explain the original magnetic properties of these compounds and for the determination of the exchange interaction in theoretical models, the Fe and Co sites and occupancies in the crystallographic structures are required. However, standard XRD can not be used to determine Fe substitution sites, because Co and Fe have too close X-ray atomic scattering factors. Results from neutron diffraction and electronic band structure calculations from our previous works were incomplete or limited. Consequently, we give in this study the characterization of the local structure by X-ray absorption spectroscopy (EXAFS) at the iron K edge. By this method, and if we assume a unique preferential site, it was determined that Fe atoms preferably occupy the 18 h site. In order to obtain this result, a coordination sphere around Fe sites of R = 5.2 Åhad to be considered in order to find sufficient local differences between the possible sites (18 h , 6 c and 3 b). Furthermore, we provide complementary magnetic properties measurements for PrCo 3 - x Fe x (x ⩽ 0.75) such as the coercive field H C , which decreases with iron content from 12 kOe for PrCo 3 to 1.5 kOe for PrCo 2.25 Fe 0.75 . The magnetization at saturation M S increases from 69 A m2/kg to 89 A m2/kg and the calculated anisotropy field H a decreases from 15.6 kOe to 11.2 kOe for the same compositions.

Here, it is reported the study of the structural, magnetic properties and magnetocaloric effect (MCE) of the Eu 2 CuSi 3 compound. Polycrystalline Eu 2 CuSi 3 compound with AlB 2 -type derived hexagonal structure was successfully synthesized by arc-melting method. Magnetic measurements indicate a second-order ferromagnetic (FM) phase transition below 40 K. The effective magnetic moment of Eu is reduced compared with divalent free ion, indicating a compensation of Eu magnetic moment. Spin reorientation induce negative magnetocaloric effect below Curie temperature. The values of full width half-maximum of −ΔS M peak ( δT FWHM = 35 K) and maximum value of entropy change ( − Δ S M m a x ∼9.5 J/kg K) for μ 0 ΔH = 6 T strongly contribute to improve the relative cooling power ( R C P ∼332 J/kg) of Eu 2 CuSi 3 compound. As observed, δT FWHM value is sensibly wider than the usual values observed for first and second order magnetic phase transition compounds. Then, − Δ S M m a x and δT FWHM values as well as the neglected magnetic hysteresis that were obtained for Eu 2 CuSi 3 have shown features as a desirable second order magnetic phase transition compound for low temperature magnetic refrigeration.

The Gd x Ho 3−x Al 2 ( x = 0.5–2.5) compounds undergo two successive magnetic transitions: a second-order magnetic transition from paramagnetism (PM) to ferromagnetism (FM) around T C followed by a FM to ferrimagnetism (FIM)-like transition at T t . The T C increases linearly with the increase of Gd content due to the de Gennes factor of Gd being larger than that of Ho, while the T t remains nearly constant around 45 K independent of the variation of Gd content. The working temperature range is expanded by substituting Ho with Gd atoms due to the higher transition temperature of Gd 3 Al 2 and the different composition dependence of successive magnetic transitions, and thus leading to an enhanced refrigerant capacity ( RC ). For a relatively low field change of 2 T, a giant RC value of 272 J/kg with a wide working temperature range of ∼80 K is obtained for x = 1.0 compound due to the partial overlap of successive Δ S M peaks. This is probably the largest RC value so far reported in the temperature range of liquid natural gas (111 K). Consequently, the large Δ S M and giant RC suggest that Gd x Ho 3−x Al 2 compounds could be good candidates of magnetic refrigerants in a wide temperature range. [ABSTRACT FROM AUTHOR]

Structural, electronic and magnetic properties of Heusler compounds CoFeTiGa 1− x Sb x have been studied. X-ray diffraction patterns show that CoFeTiGa 1− x Sb x ( x =0.25, 0.5, 0.75, 1) crystallize into LiMgPdSn-type structure. First-principles calculations indicate that CoFeTiGa 1− x Sb x ( x =0.25, 0.5, 0.75, 1) are half-metal with considerable minority band gaps. The substitution of Sb for Ga gives rise to the spin moments of the compounds, and makes them to be half-metallic ferrimagnets. [ABSTRACT FROM AUTHOR]

Structural, magnetic and magnetocaloric properties for low-cost iron-based new pseudo binary nanocrystalline compounds (Pr,Dy)Fe 9 has been investigated in detail. Four alloys with nominal composition Pr 1− x Dy x Fe 9 ( x = 0.0625, 0.125, 0.1875, 0.25) were prepared. X-ray diffraction (XRD) coupled to Rietveld analysis with FULLPROF computer code show that the samples crystallize in the hexagonal P 6/ mmm phase, derived from CaCu 5 , with the stoichiometry 1/9. The diffraction domain sizes derived from Rietveld analysis are confirmed by transmission electron microscopy. The effect of Dy substitution on the Curie temperature T C , the saturation magnetization M s and the magnetocrystalline anisotropy K is studied. The Landau coefficients, the Arrott plots and the magnetic entropy change Δ S M around the second-order magnetic transition were determined by measuring the magnetic properties. The Magnetocaloric effect properties in these compounds are comparable to that of gadolinium, which is very expensive for domestic use. [ABSTRACT FROM AUTHOR]

The full-potential all-electron linearized augmented plane wave plus local orbitals (FP-LAPW + lo) method, as implemented in the suite of software WIEN2K, has been used to systematically investigate the structural, electronic, elastic, and magnetic properties of the half-metallic ferromagnetic Heusler compounds with 4d transition elements CoYSi, CoZrSi, and alloy Co2YZrSi presented. The theoretical formalism used is the generalized gradient approximation to density functional theory (GGA) with the Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. The calculated lattice parameters and magnetic moments agree well with the available theoretical results. The spin-polarized density of states (DOS) of CoYSi and CoZrSi indicate a half-metallic behavior with vanishing electronic density of states for minority spin at the Fermi level, which yields a perfect spin polarization while for CoYZrSi shows a nearly half-metallic behavior with small spin-down electronic density of states at the Fermi level.

Plane-wave pseudo-potential methods based on density functional theory are used to study the electronic structures, magnetic properties, and half-metallicity of new predicted Ti-based full Heusler alloys TiRhZ (Z = Al, Ga, In). The CuHgTi-type structure is observed to be more favorable than the AlCuMn-type structure for these alloys. They are half-metallic ferrimagnets with total magnetic moment of 2.00 μ per formula unit and follow the Slater-Pauling rule. Also, results show that these TiRhZ (Z = Al, Ga, In) alloys have an indirect band gap with values of 0.577, 0.696, and 0.616 eV, respectively, in the minority spin channel. Two types of structural changes are used to test the sensitivity of half-metallicity. Moreover, the whole alloys investigated in the current work have a negative formation energy, which means they are thermodynamically stable. [ABSTRACT FROM AUTHOR]

First-principles electronic structure calculations have been performed for the 18-valence electrons compounds Mn 2 Si 1− x Ge x ( x =0, 0.25, 0.5, 0.75, 1). The results suggest that Mn 2 Si 1− x Ge x compounds in C1 b structure are half-metallic fully compensated ferrimagnets. Furthermore, the size of the half-metallic band gap, the position of the Fermi level, and the magnetic moment of Mn atoms can be manipulated by changing x from 0 to 1 without destroying the half-metallic fully compensated ferrimagnetic property.

In this work, first-principles calculations of the structural, electronic and magnetic properties of Heusler compounds Fe 2 MnAl, Fe 2 MnSi and alloy Fe 2 MnSi 0.5 Al 0.5 are presented. We have applied the full-potential linearized augmented plane waves plus local orbitals (FP-L/APW+lo) method based on the density functional theory (DFT). For the exchange and correlation potential the generalized-gradient approximation (GGA) is used. It is shown that the calculated lattice constants and spin magnetic moments are in good agreement with the available theoretical and experimental data. The calculated atomic resolved densities of states of Fe 2 MnAl, Fe 2 MnSi indicate half-metallic behavior with vanishing electronic density of states for minority spin at the Fermi level, which yields perfect spin polarization while for Fe 2 MnSi 0.5 Al 0.5 shows nearly half-metallic behavior with small spin-down electronic density of states at the Fermi level.

In this work, we present a study focused on the effect of partial substitution of Co by Fe on structure and magnetic properties of nanocrystalline Pr2Co7. These compounds were synthesized by mechanical alloying and to correlate their properties with microstructural evolution, a multi-scale study by: X-ray diffraction (XRD), transmission electron microscopy, and magnetization was carried out. The Rietveld analysis of XRD diagrams shows that Pr2Co7− xFe x, annealed at 973 K, mainly adopt a hexagonal Ce2Ni7 type structure with P63/ mmc space group. These pseudo-ternary compounds exhibit more interesting magnetic properties than the binary Pr2Co7 compounds. A systematic study of the intrinsic magnetic properties of these alloys shows that the substitution leads to enhancement of the Curie temperatures ( TC) by 26% for a Fe content equal to 0.5. This increase is due to the electronic as well as the magnetovolume effects. In addition, the study of extrinsic magnetic properties of the Pr2Co6.5Fe0.5 compound has revealed the existence of a large coercive field Hc, and a high remanent magnetization Mr. Our results show that in these alloys, iron in solid solution has a strong effect on hardness and ordering temperature, which is particularly promising for permanent magnet applications.

Abstract: We have studied nanocrystalline of PrCo3−x Fe x prepared by high energy milling technique. The as-milled samples were subsequently annealed in the temperature range from 873 to 1273K for 30min in order to optimize their extrinsic properties. Their structural and magnetic properties were investigated by means of X-ray diffraction (XRD) coupled with Curie temperature determination and magnetization measurements. These compounds crystallize in the PuNi3-type structure (space group: ) for . The composition is in a three phase field Pr(Co,Fe)3, Pr2(Co,Fe)17 and Pr(Co,Fe)2, for , and then is in two phase field Pr2(Co,Fe)17 and Pr(Co,Fe)2 for larger x. The Rietveld refinement showed that the substitution of cobalt by iron leads to an increase of the unit cell volume. The Curie temperature (T C ) of the PrCo3−x Fe x samples increases from 350K for PrCo3 to 580K for PrCo2Fe, the enhancement of T C is ruled by electronic and magnetovolumic effects. From X-ray studies of magnetically aligned samples, the magnetic anisotropy of these compounds changes from the c-axis to the cone anisotropy. The magnetization of the compounds increases as cobalt is replaced by iron and no saturation reached at room temperature for an applied field of 90kOe. The hard magnetic properties are obtained after annealing at 1023K for 30min where the coercivity achieved H C =5kOe. [Copyright &y& Elsevier]

Abstract: In this experiment, a Co60Fe20B20 target is used to deposit a monolayered Co60Fe20B20 thin film on glass substrate by dc magnetron sputtering to a thickness of 1000–5000Å under the following conditions; (a) the substrate temperature (T s) is maintained at room temperature (RT), (b) post-annealing at T A =150°C for 1h, (c) post-annealing at T A =250°C for 1h, and (d) post-annealing at T A =350°C for 1h. This study analyzes the thermal, magnetic, electric, and adhesive properties of amorphous Co60Fe20B20 thin films with thicknesses from 1000 to 5000Å using the sputtering method. X-ray diffraction (XRD) reveals that each Co60Fe20B20 thin film had an amorphous structure at room temperature. XRD demonstrates that post-annealing treatment made the CoFeB films more crystalline or nanocrystalline. To elucidate the transformation of an amorphous CoFeB film to a crystalline structure, Kissinger’s formula is used to calculate the activation energy (Q) of crystallization. The results indicate that activation energy has a concave-up feature and the critical thickness of activation energy is 3000Å in the amorphous state. The 3000Å-thick of as-deposited CoFeB film forms a crystalline state more easily than any other film. The plots of the magnetic properties, including low-frequency alternative-current magnetic susceptibility (χ ac), saturation magnetization (M s), and remanence magnetization (M r), are concave-down feature. The results concerning the χ ac properties of CoFeB films indicate that post-annealing at 150 and 250°C increases because of magneto nanocrystalline anisotropy. And the 3000Å-thick of each condition is a critical point. However, post-annealing at T A =350°C for 1h reduces χ ac by disturbance, weakening magnetic spin coupling. In addition, the M s and M r results of each condition show the similar trend to χ ac. The electrical resistivity (ρ) of the as-deposited film exceeds that of the post-annealed films because the grain boundaries and the surface scatter the electrons, so the as-deposited film has a higher ρ than the post-annealed films. Thinner films also have a higher ρ. The surface energy and adhesion of the CoFeB films follow the same trend as the fitter Kissinger plot. This result suggests that stronger crystallization is associated with a lower surface energy and weaker adhesion. The surface energy plot exhibits a concave-up feature and the critical thickness is 3000Å in all cases. Based on the above properties, CoFeB films can be utilized in magnetic recording media, semiconductors, and seed layer applications. [Copyright &y& Elsevier]

Abstract: Using high-energy ball milling, nanostructured Pr2Co7 powders can be obtained from their arc-melted bulk alloys. The structure and the microstructure properties were studied by X-ray diffraction and transmission electron microscopy. The crystallization, phase components and magnetic properties of these alloys were investigated systematically. Structural and magnetic measurements reveal different phases for specific annealing temperature ranges. For samples annealed at T a =1023K, the main phase is hexagonal of the Ce2Ni7 type structure whereas at T a =1323K, the main one is rhombohedral of the Gd2Co7 type structure. The autocoherent diffraction domain size derived from Rietveld analysis, varying between 6 and 40nm, are confirmed by transmission electron microscopy. The coercivity increases with annealing temperature reaching a maximum for T a =1073K, the highest value is equal to 18kOe at 293K and 23kOe at 10K. This coercivity is attributed to the high magnetocrystalline anisotropy of the Pr2Co7 phase and its optimized nanoscale grain size. The remanence ratio M r/M max is equal to 0.64. Thermomagnetic measurements indicate that the intermetallic Curie temperature (T C) is about 600K for hexagonal phase and 580K for rhombohedral one. These properties are suitable for permanent magnet applications. [Copyright &y& Elsevier]

Abstract: First-principles calculations have been carried out to study the electronic structure and magnetic properties of the Fe3Zn compound with the full-potential linearized augmented-plane wave (FLAPW) method. The results indicate a lower magnetostriction for Fe3Zn as compared to Galfenol (Fe–Ga), as a result of a weaker spin–orbit coupling, which is due to a smaller magnetic moment induced on the Zn atom. With the Zn addition to Fe the bulk modulus and the cohesive energy (per atom) decrease, whereas the electronic specific heat coefficient has a substantial increase. [Copyright &y& Elsevier]

Abstract: Magnetic properties of (Fe0.72B0.24Nb0.04)95.5Y4.5 sample were investigated. The sample was produced from glassy powders made by the gas-atomization and consolidation using the spark plasma sintering (SPS) technique. Maximum relative density of 99.5% was achieved in the spark plasma sintered (SPSed) compact due to the viscous flow enhanced by the applied stress even under the glass transition temperature. X-ray diffraction pattern of the compact indicates that the glassy structure was maintained through the SPS process. However, the results of differential scanning calorimetry (DSC) showed that the glass transition temperature and crystallization temperature of the SPSed glassy compact shift to a higher and lower temperature, respectively, that is, a smaller ΔT x. Saturation magnetization of the SPSed glassy compact became 10% higher than that of the initial glassy powder. The Curie point was enhanced from 522K for the glassy powder to 548K for the SPSed glassy compact. Spin-exchange interaction is expected to be enhanced by a short-range scale atomic rearrangement caused by the high applied stress and temperature during the SPS process. [Copyright &y& Elsevier]

Fe3Si polycrystals having a large initial grain size of about 92 μm exhibit a large tensile elongation exceeding 200% at 1173 K and at 4.68×10−4 s−1. A stress–strain curve corresponding to the large tensile elongation is characterized by a steady state flow after an initial work hardening at a small plastic strain until final fracture. The apparent activation energy and strain rate sensitivity index is estimated to be 120 kJ/mol and 0.30, respectively. The deformation microstructure responsible for the large elongation consists of a well-defined subgrain microstructure with a low dislocation density within dynamic recrystallization (DRX) grains evolved during high temperature deformation. Large elongation is achieved by glide motion of 〈001〉 type dislocations. It is suggested that glide and climb motion of 〈001〉 type dislocations leads to simultaneous and/or alternate occurrence of DRX and dynamic recovery (DRV), which retards the initiation of plastic instability and results in large elongation.
