Abstract

Using a statistic E-J model describing percolative current transport properties, we analyzed pinning strength, its distribution and angular dependence of Bi-2223 Ag-sheathed tapes. It has been shown the anisotropy can be attributed to angular dependence of the depinning transition field, and a scaling holds with respect to the pinning force density. The angular dependence of the transition field can be described precisely by an extended Tinkham 2D model taking into account misalignment angle of the filaments. We driven an analytical expression describing the magnetic field and angular dependence of Jc and n value of the tape. It allows us to predict the angular dependence of the transport properties using only limited data set, i.e., 1) magnetic field dependence in perpendicular field and 2) anisotropic ratio of the transition fields between perpendicular and parallel configuration.
