As is well known, the unique structural feature connecting the various high T c materials is the presence of copper oxide planes1. By varying the out-of-plane constituents these planes may be doped into the metallic and eventually superconducting state. In the insulating phase, the Cu 2+ sites have a spin of 1/2 and order antiferromagnetically in the ground state, as determined, for example, by neutron scattering2. Since La2CuO4 exhibits the simplest crystal structure of the high T c materials, much effort has been focused on this and isostructural systems, in the hope of avoiding irrelevant complications. The schematic phase diagram, shown in Fig. 1, however, demonstrates that even the nominally simpler La2CuO4 system exhibits a rich variety of behaviors.
