Abstract

Based on Persson's [Surf. Sci. 258 (1991) 451] idea the concept of linear relaxation with respect to the strongest interaction between adsorbates is established. This simple but powerful concept not only destroys the characteristic but unrealistic particle-hole symmetry of all pairwise-potential models, as already shown by Persson, but introduces at least one new phase into the Ising antiferromagnetic model on the simple quadratic lattice and distinguishes between the p(2 × 2) and the c(4 × 2) phases without the need of third-neighbor interactions. The ground state phase diagram for the antiferromagnetic Ising model including nnn interactions and relaxation as well as methods of estimating the magnitude of the relaxation effect to be expected are given.
