Abstract

Systematic investigation of a recent proposal of Rapaport (1985) to describe the Heisenberg model with discrete spin models is presented in two and three dimensions. It is argued that in three dimensions a 12-state discretisation already accounts satisfactorily for the critical properties, the corresponding anisotropy operators being irrelevant.
