Abstract
We discuss phase diagrams and concentration variations near surfaces of fcc alloys on the basis of replacing the Weiss field, in the Bragg-Williams approximation, by the Onsager Cavity field. We argue that this scheme is as tractable as the Mean Field Approximation for complex problems and provides an adequate account of correlations even in frustrated systems.
