摘要：
By analyzing the flux-line dynamics and the critical current density as a function of temperature and magnetic field in Tl2Ba2Ca2Cu3O10 single crystals, we have identified different pinning regimes. We have shown that the break in slope in the j(c) vs. T curve at T=T-CR may be caused by the crossover from the strongly dispersive small-bundle to the weakly dispersive large-bundle collective pinning.
