An application of the dynamical mean-field approximation to ferromagnetic alloys

Research output: Contribution to journalArticle

Abstract

The effect of the fluctuation of local correlation in the phase diagram of binary ferromagnetic alloy is investigated by using the coherent potential approximation and the dynamical mean field approximation. The Curie temperature varies smoothly as the function of the concentration. This behaviour is different from the phase diagram which is calculated by the Hartree-Fock approximation.
