摘要：
We measured the temperature dependence of the ac susceptibility in Bi2Sr2CaCu2O8 single crystals. The penetration fieldH* was determined, at different temperatures, from the field dependence ofX″ in the framework of the critical state model. Using a very simple formula, we estimated the values of the critical current density near Tc, which are consistent with the usually reported data for this material.
