Anisotropic ordering in binary alloys

The problem of ordering in a binary alloy with anisotropic interaction between atoms is analyzed in the Kirkwood approximation. It is shown that the emerging oriented superstructure does not depend on the isotropic component of ordering energy. Transition to the ordered state destroys the short-range anisotropy. The constant of induced magnetic anisotropy is calculated for a ferromagnetic alloy, while its dependence on the alloy composition and the degree of far-range order as well as on the anneal temperature and the test temperature is established.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 109–112, March, 1976.
