摘要：

Measurements of irreversible magnetization in the superconducting state of the Bi2Sr2CaCu2O8 compound have been made using a dc magnetometer. It was found that the irreversible magnetization is proportional to (T - T*)n, where T* is the field-dependent irreversibility temperature and the power n is of the order of 5. The irreversibility temperature obeys the relation 1 - T*/T(c) is proportional to B2/3 at fields up to 0.6 T. At higher fields, T* was found to vary more slowly with the field, which is in agreement with previously published results.
