Abstract

The discontinuous (first-order) transition behaviour of compressible Ising systems described by Hamiltonians of the form H=−Js Sigma(ij)SiSj−J4 Sigma (ij) Sigma (kl)SiSjSkSl has been studied for the first time using Monte Carlo techniques for lattices of sizes 1002 and 203. The results have been compared with those obtained using the renormalisation group technique.
