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.eninfo:eu-repo/semantics/openAccessHalf metallicFerromagnetismDouble perovskitesSr2FeHfO6 alloySpintronicsArticle10.1016/j.jmmm.2020.167374518Q3WOS:0006436905000092-s2.0-85092243489Q2
