Abstract
The order-disorder transition at the surface of fcc Ising antiferromagnets and binary alloys is studied in the mean-field approximation. Several generic features of wetting in ordering alloys and magnets with short-range interactions are elucidated. The salient feature of the model is that more than one density is needed to describe the ordered state. This makes it possible to study the influence of surface segregation and is found to lead to qualitatively new nonuniversal wetting behavior.Keywords
