Abstract

In order to evaluate the effect of the microstructure on E-J properties, the E-J properties for Bi2212 thick films prepared under three different conditions were measured. The measured E-J properties were analyzed based on the percolation model, and the local Jc (Jcl) distribution was evaluated. The distribution of the local Jc was much affected by its microstructures. For the well aligned sample with large plate-like grains, which is similar to Ag-sheathed Bi2212 tape, the distribution of the local Jc at percolation transition field BGL was found to be asymmetric and reached the high Jcl region.
