Abstract

E-J properties of the high-Tc superconductors are related to the distribution of the flux pinning strength and the local critical current density Jcl. From the previous result of Bi2212 thick films, we found that the distribution of the local Jc is much affected by microstructures, and the local Jc 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 Jc distribution was investigated.
