dc.descriptionThe anomalous depinning of Josephson interlayer vortices in Bi2Sr2CaCu2O8 high-T-c superconductor occurring at nearly field-independent temperature T-x=20-40 K has been studied by means of ac susceptibility measurements with magnetic field applied parallel to CuO2 planes. From the frequency dependence T-x(v(m)) we define the flux-creep activation energy for Josephson vortices U-JV(H) which increases with field and shows well-defined plateaus. In contrast, the activation energy of in-plane pancake vortices U-PV(H) decreases with field, i.e., demonstrates a qualitatively different behavior.
