Abstract
Fully relativistic investigations on the magnetic circular dichroism in emi ssion have been performed for Rh in the three alloy systems Co0.75Rh0.25, C o0.75-xRh0.25Nix, and Co0.75Rh0.25-xPdx. The results obtained using the spi n-polarized relativistic Korringa-Kohn-Rostoker method of band-structure ca lculations together with the coherent-potential approximation (SPR-KKR-CPA) allow one to make a detailed interpretation of corresponding experimental data. The changes in the magnetic moments of Co and Rh in the binary alloy CoxRh1-x caused by substitution of Pd for Ph and Ni for Co, respectively, a re discussed in comparison with experimental data and a generalized Slater- Pauling curve.
