Abstract
Transport measurements in the mixed state of crystals (H∥c) using the ‘‘dc-flux-transformer’’ configuration show that the glass-liquid phase transition at the irreversibility line, (H), behaves as a three-dimensional vortex phase transition. These results together with resistance measurements in the c direction show that the vortex correlation across the sample is destroyed at a temperature (H), higher than (H). However, the dependence of (H) on sample thickness suggests that, in real thermodynamic phase transitions (infinite sample), the long-range correlation in the ab plane, as well as in the c direction, is lost at the single temperature (H).
