Abstract

The main results of the systematic study of the electron transport properties and AC susceptibility in Pb-doped, almost single phase, Bi 2223 ceramic samples and Ag-clad Bi 2223 tape, are presented. Whereas the results for the ceramic samples can only be used for the study of the percolation problem in the weak-link network, those for tape can yield some intrinsic parameters of Bi 2223 compound (the upper critical fields B_C2, the coherence lengths, etc.). In addition, the results for the tape provide some technologically relevant parameters (the pinning potential U_0, volume pinning force F_p and the flux-flow viscosity h) and an insight into the nature of dissipation and pinning in these materials. Some factors limiting the critical current density J_c in the present-day tapes are briefly discussed.
