PINNING-FORCE SCALING AND ITS LIMITATION IN INTERMEDIATE AND HIGH TEMPERATURE SUPERCONDUCTORS

摘要: We present the scaling law of pinning force FP in intermediate and high temperature superconductors, factors which influence its field dependence, limitations imposed by enlarged anisotropy operating temperatures, giant creep included. The theoretical developments incorporate new features these classes most them based on Anderson–Kim theory, prove to be a useful source information relative nature characteristic fields. use models thermal activation integrates into tail also substantiates irreversibility Hirr as scale field. Finally, data two class superconductors are presented discussed.
