摘要：

The relaxation of the remanent moment induced in a nearly single-phase high Tc thin film of Pb-doped Bi-Sr-Ca-Cu-O has been investigated. Measurements reveal that the relaxation obeys a logarithmic time dependence for observation intervals up to 2000 s. The temperature dependence of the initial magnetization and its decay rate are obtained. The decay rate normalized by initial magnetization exhibits a peak around 14 K. The peak shifts to lower temperature for stronger magnetic field. These data are compared with existing data on other high Tc superconducting materials.
