Phys. Rev. B 50, 11146–11150 (1994)Surface melting and layering transitions from a lattice-gas modelReceived 18 May 1994; published in the issue dated 15 October 1994 We have studied the surface behavior of the Blume-Emery-Griffiths model within the mean-field approximation, interpreting the model as a lattice gas. The solid surface exhibits a series of first-order layering transitions, and wetting phenomena are found all along the first-order part of the solid-liquid bulk coexistence line. We present a complete phase diagram of the solid surface and discuss the various kinds of surface behavior observed near bulk melting. © 1994 The American Physical Society URL:
