Abstract

The LMTO method of Greens functions in the atomic sphere approximation is used for self-consistent spin-polarization calculation of the electron structure of equiatomic alloys FePd, FePt, CoPt and MnAl; the angular distribution of the spin density of the Fe atom in FePd is obtained; the spin magnetic moments of the alloy components are determined. For FePd, FePt and CoPt the reduced orbital moments arising on the atoms as a result of spin-orbital interaction are calculated. For alloy MnAl with a small Mn excess the energetically preferred state of the impurity Mn atom is found to be in an Al site with magnetic momentum antiparallel to that of the surrounding atoms. That momentum is slightly greater in value than that of the Mn atom in the equiatomic alloy. The influence of carbon as a substitutional impurity is examined with regard to the electron structure of alloy MnAl.
