Abstract

E-J properties of the high-T_c superconductors are related to the distribution of the flux pinning strength and the local critical current density J_cl. From the previous result of Bi2212 thick films, we found that the distribution of the local J_c is much affected by microstructures, and the local J_c distribution becomes broad and asymmetric for well aligned plate-like Bi2212 grains. These microstructures are similar to the case of practical Ag sheathed Bi2212 tapes. In this study, we performed E-J measurements of practical Ag sheathed Bi2212 tapes at various temperatures and magnetic fields, and the local J_c distribution was investigated.
