Fig. 2. Commonly observed electronic phase diagram of the high-temperature superconductors. The superconducting (SC) region spreads over the hole concentration p per CuOj unit from 0.05 to 0.28, showing the maximum at 0.15. Below p=0.02, the antiferromagnetic (AF) phase is obtained. To is die temperature below vshich various properties show anomalies with respect to the Fermi hquid, while below T a gap is thought to open up in the spin excitation spectrum.
