摘要：

The temperature dependence of the comlex ac susceptibility of YBa2Cu3O7-delta (YBCO) thin films is presented for a range of ac fields normal to the surface. The results are modelled using a critical state model as presented by Sun et.al.in ref[1]. Using a power law temperature dependence of the critical current J(c)(T) the measured curves can be fitted to the theoretical ones and this dependence can be extracted.
