摘要：

The electrical resistivity of a single-crystal sample of YBa2Cu3O7-δ has been measured. The results are consistent with the existence of a critical regime governed by three-dimensional XY critical exponents. Evidence is also found for the divergence of the conductivity along a line Hg(T)(1-T/Tc)2ν, the vortex glass transition line. The vortex glass exponents characteristic of this line are zg(νg-1)5±1. The results are not consistent with the lowest Landau-level scaling. © 1995 The American Physical Society.
