Electronic structure and magnetic properties of dilute Co alloys with transition-metal impurities

Abstract
We present ab initio nonrelativistic and relativistic calculations for fcc Co alloys with 3d and 4d elements. The calculations are based on the local-density approximation of density-functional theory and employ the Korringa-Kohn-Rostoker Green’s-function method. Results are given for the density of states, the local moments and hyperfine fields of the impurities and their nearest neighbors. The calculated magnetic moments and hyperfine fields are in reasonable agreement with the experimental data.
