Abstract
We have developed a first-principles electronic theory of concentration fluctuations in spin polarized binary alloys. It is a mean field theory of the state of compositional order and it is based on the local spin density (LSD) approximation for describing the electrons. The usual averages over the statistical mechanical ensemble are carried out with the aid of the self-consistent Korringe–Kohn–Rostoker coherent-potential approximation (SCF-KKR-CPA). To illustrate the main consequences of the theory we study the compositional short-range order in the NicFe1−c alloy system. We find that the ordering energy is almost entirely of magnetic origin.
