摘要：

A first-principles theory of alloy ordering in two and three dimensions in the presence of ferromagnetism is described. Using the generalized perturbation method, the order-disorder transition from the bcc Fe50Co50 random alloy into the ordered CsCl-structure FeCo alloy and its ordering temperature are found to agree reasonably well with available experimental data. A similar ordering tendency for the formation of the ordered c(2 x 2) phase of the Fe50Co50 surface alloy on fcc Cu(001) is investigated.
