摘要：

The voltage-noise measurements in epitaxial YBa2Cu3Ox films have been extended to the case of a high magnetic field. In a magnetic field, two noise peaks, one from the vortex motion and the other from the resistance fluctuations, were observed. The location of the vortex-motion induced peak was found to be well above the vortex-glass transition. Our interpretation is that a noise peak manifests itself in a crossover from the pinned vortex-liquid to the unpinned vortex-liquid state.
