Abstract

The chemical, ordering and magnetic properties of binary alloys at the surface are examined in terms of a model of pairwise interacting atoms. Both the case of segregating alloys and the case of alloys which form intermetallic compounds are examined. Some surprising results about surface concentration and surface ordering are found. Applications to a number of systems, including ferromagnets, are presented.

21. It should be noted that the minimization procedure should be conducted by differentiating F with respect to all η and σ parameters, considered as independent variables, but keeping all xn as constants. Once all the order parameters are expressed in terms of xn and replaced in the free energy expression, then the constraint conditions (2.12) should be applied to determine the equilibrium values of xn and all order parameters.Google Scholar
