摘要：

The irreversibility line of silver-sheathed Bi-2223 tapes and of melt-processed Bi-2223 samples doped with Te has been investigated by AC susceptibility, DC magnetization and transport measurements. The temperature dependence of the irreversibility field B* follows a relation B*(T) proportional to (T-c/T-1)(1/n) with n=0.6 which can be interpreted in the framework of a flux-creep model with an expression for the activation energy U proportional to (1-T/T-c)/B-n.
