Influence of alloy composition and local environment on the magneto-optical properties of ${\mathrm{Co}}_x{\mathrm{Pd}}_{1-x}$ alloys

Results of ab initio calculations performed to investigate the dependence of magneto-optical properties of ${\mathrm{Co}}_x{\mathrm{Pd}}_{1-x}$ alloys on chemical ordering and alloy composition are presented. A procedure of averaging the calculated spectra for compounds with respect to the orientation dependence of the gyration vector is proposed that makes it possible to account for the effects of random orientation of microcrystals in polycrystalline samples. Good agreement between theoretical and experimental spectra for varying alloy composition is found demonstrating the applicability of the theoretical approach.
