dc.description.abstractStrong spin-orbit coupling (SOC) in Sr2FeHfO6 (SFHO) alloy has been predicted by means of full-potential linear augmented plane wave method in order to study the effect on electronic structure. The tetragonal (I4/mmm) SFHO with SOC has an up-spin energy of similar to 1.2 eV and a total magnetic moment of similar to 2.03 mu B mainly coming from the Fe (1.63 mu B), and the SOC effect was prominent in SFHO due to the magnetic moment of 3d-Fe orbitals. The XAFS spectroscopy technique was used in order to analyze the electronic structure and optical properties of SFHO. The absorption spectra with Fe as a source atom shows a peak appearing around 7118 eV. SFHO with SOC falls within the half metallic state in the up-spin direction resulting significant increase of the total magnetic moment. This half-metallicity strong SOC in SFHO demonstrate much spin polarized electrons around the Fermi level, hence, this material is very potential in future memory devices and spintronic applications.
