Аннотация

The Kikuchi cluster variation method is used to consider atomic and magnetic ordering in fcc alloys. An order-disorder phase equilibrium diagram is plotted theoretically for a binary alloy in which the atoms of one component interact antiferromagnetically. The influence of the antiferromagnetic interaction of the components on the nature of the order-disorder transformation is elucidated for compositions of various stoichiometry. The possible existence of a ferromagnetic phase in the presence of a strong antiferromagnetic interaction is demonstrated for alloys having about 25 at. % of the magnetic component. The behavior of the magnetization and the Curie temperature found by calculation suggests that precisely this situation (ferromagnetism due to strong antiferromagnetic interaction of one of the components) exists in the alloys MnNi//3, MnPt//3, MnPd//2, CrPt//3, and other alloys containing manganese or chromium.
