Abstract
First-principles calculations of the electrical conductivity of disordered ferromagnetic alloys based on the Kubo-Greenwood formalism and the spin-polarized relativistic Korringa-Kohn-Rostoker coherent-potential-approximations method are presented. Application to the alloy systems Co-Pd and Co-Pt yields results for the isotropic and anisotropic residual resistivity which are in very satisfying agreement with experiment. In addition, scalar-relativistic calculations of the isotropic residual resistivity were performed on the basis of the two-current model for these alloy systems, and were found to agree with the relativistic results fairly well. © 1996 The American Physical Society.
