Abstract
We discuss the temperature-concentration (T−x) phase diagram of La2−x (SrBa) x CuO4. The magnetic interactions of the hole spins with the Cu spins yield frustration, explaining the fast decrease in the Néel temperature and yielding a new spin glass phase. The same interactions yield a strong attractive hole-hole potential, which can lead to pairing and superconductivity.
