The experimental data were analyzed to determine the current-dependent energy barrier, U(J), following a method proposed by Maley et al. The result was further investigated on the basis of weak collective pinning theory. It was found that the result of analysis on the temperature-dependent data was consistent with the theoretical description of thermal-disorder induced-interlayer-decoupling transition of the vortices, while its field-dependent data reveal the characteristic feature of elastic-plastic crossover of the vortex motion. © 2004 Elsevier B.V.
