摘要：
Numerical simulations for an XY-spin-glass model are presented. The connection to recent experiments on high-Tc superconductors is outlined. In particular, the glass behavior in experiments is reproduced by a two-dimensional (2d) model. A phase diagram important for future experiments is also provided. A substantial gain in Tc is predicted for enhanced couplings between plains.
