Abstract
A theory of the residual electrical resistance of ferromagnetic disordered alloys is presented in the framework of the coherent-potential approximation. It generalizes a previous calculation made for a two-band model Hamiltonian relevant for transition-metal-based alloys. This formalism can be applied to calculate the concentration dependence of magnetization, spin-up and spin-down resistivities, and spontaneous resistivity anisotropy of ferromagnetic alloys. These quantities are computed for a simple model of NiCu and are found to be in good agreement with observation.Keywords
