Description

We report on a comparative study of the vortex dynamics in crystalline and melt processes ceramic Bi2Sr2CaCu2O8 by ac susceptibility, which is described within the model of Thermally Activated Flux diffusion (TAFF). In the limit of small current densities the resulting activation energy U is independent of J and the temperature and field dependences of U show evidence for diffusion of two-dimensional vortex lattice defects.
