The influence of external uniaxial pressure, ranging from 0 GPa to 50 GPa, on (3,0)(6,0) carbon (C3060), is examined through first-principles calculation. The mechanical descriptors, including elastic constants, bulk modulus, shear modulus, and Young's modulus, are studied and reported. Moreover, these characteristics demonstrate the adaptable robustness of C3060 to mechanical stress under various pressure conditions. Also, the ductility and brittleness analysis is obtained based on Cauchy pressure, Poisson's ratio, and Pugh's criteria. The structural and dynamical stability of C3060 are ensured using cohesive formation energy, phonon band spectrum, and phonon density of states. Further, the thermodynamic properties of C3060 under high pressure are discussed with regard to Gibbs free energy and entropy. Also, the electronic properties of C3060 under pressure within the range of 0 GPa–50 GPa are explored based on the band structure and projected density of the state spectrum. In short, this work emphasizes how uniaxial pressure influences the mechanical characteristics and electronic attributes of C3060, providing information on the adaptability of the material's structural features with regard to mechanical attributes.

We present the temperature and magnetic-field dependencies of the c-axis magnetization of a UCoAl single crystal under various uniaxial pressures exerted along the c-axis. The main result obtained is the uniaxial-pressure-induced reduction of the critical field of the metamagnetic transition followed by the formation of ferromagnetism at higher uniaxial-pressures. These and other associated results are discussed in comparison with corresponding data obtained by applying hydrostatic pressure on the same material. A scenario considering a variation of the anisotropic 5f-ligand hybridization and its consequences induced by the two different types of applied pressure is an important base for the discussion. The pressure-induced variations of the 5f–3d hybridization within the basal plane of the ZrNiAl-type hexagonal structure seem to be the underlying aspect of the evolution of the magnetism in UCoAl.

Abstract: Strain and resistivity measurements were performed under uniaxial pressure on single crystals of (superconductive under isotropic pressure over 2GPa) to clarify the role of pressure in the ladder superconductivity. Compressibility along the uniaxial pressure is the largest in the layer-stacking direction. By increasing the compression of the layer-spacing, the ladder planes are expanded and the resistive component both along and across the ladders are found to decrease monotonically. This indicates that a charge transfer from the -chain planes to the -ladder planes is promoted by the layer compression. [Copyright &y& Elsevier]

Abstract: Uniaxial pressure effects on with and without a static-stripe instability were examined in crystals. The in-plane (out-of-plane) pressure increases (decreases) in both cases, but in a different rate. In the presence of static stripes, the -enhancement with the [110]-axis pressure is greater than that with the [100] pressure, giving rise to a novel anisotropy in the in-plane pressure effect. The -suppression with the [001] pressure is also found to be enhanced due to static stripes. These results indicate that uniaxial pressure is extremely effective in tuning the stripe instability, and can be a novel technique to control in the presence of static stripes.

Abstract: Anisotropic (uniaxial) pressure effects on were, for the first time, measured in electron-doped high-temperature superconductor . In contrast to a report that the isotropic-pressure effect is anomalously absent up to several GPa in electron-doped high- superconductors, a reduction of is observed under anisotropic pressure along the -axis within . It is also found that the effect shows a non-linear dependence on , i.e., -suppression is enhanced above . [Copyright &y& Elsevier]

We report the magnetic phase diagram of Ce3Pd20Ge6 under uniaxial pressure. It is found that the phase diagram changes considerably with pressure, but that the antiferromagnetic and ferroquadrupolar ordering temperatures do not change within experimental accuracy. [Copyright &y& Elsevier]

The resistivity ρ(T) of the heavy-fermion system CeCu6−xAux shows that for x=0.2 the Ne´el temperature TN rises under uniaxial stress σa parallel to the a-axis, in qualitative agreement with previous studies of the specific heat. For x=0.1, near the magnetic quantum phase transition, no hints of magnetic order are observed up to the highest σa of 4.5 kbar. A detailed discussion of the dependence of ρ0 on hydrostatic and uniaxial pressure is given. [Copyright &y& Elsevier]

Magnetic susceptibility χ(T) of the cubic compound Ce0.75La0.25B6 has been examined under uniaxial pressures, focusing attention on the mysterious ordered state called ‘phase IV’. While being quite isotropic at an ambient pressure, χ(T) of phase IV becomes strongly anisotropic at a relatively weak pressure of 60 MPa applied parallel to the [0 0 1] direction. A cusp remains at around the phase IV ordering temperature To(≃1.7 K) in χ[1 1 0](T) for magnetic field H||[1 1 0], whereas χ[0 0 1](T) with H||[0 0 1] shows an upturn at To and continues to increase on further cooling. Surprisingly, To under the pressure seems to increase with H||[0 0 1]. The results cannot simply be explained by ordinary antiferromagnetic states, and are discussed in view of a possible multipolar ordering in phase IV. [Copyright &y& Elsevier]
