Abstract
The antiferromagnetic, restricted, solid-on-solid model describes a surface which above its roughening temperature undergoes a transition due to the melting of looplike internal degrees of freedom. This model belongs to the same universality class as an Ising model on a two-dimensional lattice with transverse vibrations, and describes commensurate melting of monolayers adsorbed on rough substrates with annealed steps. Finite-size-scaling calculations confirm this. q-state antiferromagnetic clock models describe antiferromagnetic Ising models on lattices with dislocations of Burgers vector q.Keywords
