Abstract
The properties of a model to describe the planes in the high- superconductors are discussed in the strong-coupling limit. On the assumption that doping creates holes on the O rather than the Cu sites, following the recent suggestion of Emery, it is shown that antiferromagnetic ordering of the Cu moments will lead to either localization or pairing of the O holes. The effect of magnetic anisotropy on the pairing interaction is discussed, and it is suggested that it will strongly enhance superconductivity in these systems.
