Big Data is a technologically advanced data management tool, which is helping several multinational organizations as well as SMEs around the globe to get access to huge volumes of data related to purchasing behavior and preferences of customers in a time effective manner. The contemporary global business environment is becoming highly competitive and saturated. In order to overcome the threat of high market saturation and strong market competition, different companies are adopting digitized approaches and technological advancement in business operation activities to enhance potential competitive advantages. Quick and efficient data management has become a real concern for the present companies to improve core competency of the business. Different theoretical frameworks and models related to customer loyalty and customer experience are applied in the study. On the other hand, theoretical approaches related to the impact of Big Data on business performance of organizations are also discussed. Depending on the exploratory design of the study, qualitative research methodology has been applied by the researcher in this study. In terms of data collection process, primary data is collected by interviewing the selected respondents for this research. A simple random sampling approach has been considered in this study to decide a realistic sample size for the purpose of collection of data. Ultimately, the analysis and findings of this research work has indicated that Big Data has become an important data management tool for contemporary organizations that positively influences potential business growth of the organizations in the global market.

BaFe12O19 Nanoparticles are prepared through auto ignition method and structure, microstructure and magnetic properties are characterized. Samples having spherical shapes and elongated nanorods are chosen to investigate the role of finite size effect in magnetic properties. Magnetization studies show superparamagnetic, antiferromagnetic and ferrimagnetic behaviors depending on the size and shape. Very small coercive field of around 200 Oe is observed for spherical nanoparticles and a large coercive field of around 7000 Oe for nanorods is found. The shape and size plays an important role in magnetic properties of BaFe12O19 nanoparticles. Shape anisotropy has significant value compared to other anisotropies. Therefore shape of nanoparticles influences the magnetic order. [ABSTRACT FROM AUTHOR]

Superparamagnetic LaFeO3 nanoparticles are synthesized through sol gel method. Structural, magnetic and dielectric studies are carried out. Temperature dependent ESR studies show that the intensity of the ESR spectra increases at higher temperatures. The line shape at low temperature has inhomogeneous broadening and at higher temperature more symmetry is developed and it fits better with the Lorentzian. Resonance field decreases when temperature is lowered due to dipolar interactions and there are no extrema in linewidth are observed. Single semicircular arc in the Cole-Cole plot shows that the AC conductivity is from grains only. [ABSTRACT FROM AUTHOR]

Ferroelectric material with high dielectric constant of Ba0.5Sr0.5TiO3 is synthesized through Solid State Reaction and fraction of Lanthanum is substituted to introduce hole concentration. XRay Diffraction shows all the samples are stabilized in cubic crystal structure. With La doped samples the Cole-Cole plot is modified and AC conductivity increases at higher temperatures as well as higher frequencies compared to undoped sample. [ABSTRACT FROM AUTHOR]

Temperature dependence of Ferromagnetic Resonance (FMR) and DC magnetization measurements were carried out on Mg doped orthorhombic La0.67Ca0.33MnO3manganite. All FMR spectra are Lorentzian lineshape, however, inhomogeneous broadening with asymmetry in the signal is observed below and near Curie temperature Tc. The resonance field below T*δHPP decreases with decreasing temperature. The temperature dependence of FMR signal intensity follows the Arrhenius behavior. [ABSTRACT FROM AUTHOR]

Single crystals of mercury cadmium chloride thiocyanate [Hg3CdCl2(SCN)6; (MCCTC)] were grown from ethanol solvent using slow solvent evaporation technique for the first time. The cell parameters of the grown crystals of MCCTC were confirmed by single crystal X-ray diffraction technique. The various functional groups of resulting compound were well-identified using FT-IR analysis. The UV-Vis-NIR studies revealed that the ultra violet cut off wavelength lies at 270 nm. It is also interesting to note that the sample exhibited wide range of optical transparency from 270 to 2000 nm in ethanol solution, which might be due to the incorporation of the halogen ion (Cl-) in the grown crystal of MCCTC. The second harmonic generation efficiency of MCCTC is found to be superior (about seventeen times) to KDP and (about three times) urea. TGA-DTA and DSC analysis showed that the thermal stability of the sample is retained up to 171.3°C above which phase change occurred from HgCdCl2(SCN)6 to CdHg(SCN)4 with other fragments. The latent heat of the sample is found to be 0.7652 J/Kg. [ABSTRACT FROM AUTHOR]
