Abstract
The Fermi surface geometry and the electrical resistivity have been calculated in the framework of the fully relativistic Korringa-Kohn-Rostoker coherent potential approximation (KKR CPA) for a series of Cu-Pt alloys. Bloch spectral functions have been used to determine the position of the Fermi surface in various directions in k-space and to discuss band structure like behaviour. This information served as input data for the electrical resistivity calculation by means of a formula derived from the Boltzmann equation. The calculated electrical resistivities and the experimental data agree with each other very well.
