Abstract
A study of a simple band model of a commensurate, two-dimensional anti ferromagnet is briefly described. A self-consistent calculation shows a transition from a paramagnetic to a metallic antiferromagnetic state when an interaction is stronger than a critical value. The transition is accompanied by a change in size (large to small) of the Fermi surf ace. An insulating state may be obtained if there is exactly one elect ron per site.
