摘要：

The role of thermal vortices in the absence of applied magnetic fields is studied theoretically for anisotropic layered superconductors such as the high-Tc cuprates. Using a quasi-two-dimensional model and a real-space renormalization-group approach, the vortices are found to Josephson-decouple the superconducting layers slightly above Tc. The results are consistent with recent experiments and Monte Carlo simulations. © 1995 The American Physical Society.
