The loss peak of the AC susceptibility in polycrystalline high-To superconductors shifts slightly to higher temperatures with increasing frequency of the applied AC magnetic field. It is shown that a flux creep term, added to the current density term in the critical state equation, can account for t
The field and temperature dependent critical current density, jc(B, T), and magnetization, M(B, T), of melt processed Bi2Sr2CaCu208 samples have been examined in fields up to 8 T. In addition, published data on an epitaxially grown YBa2Cu307 film have been analysed. Both sources of information show
