Abstract

We show that the Brick Wall Model [L.N. Bulaevskii et al., Phys. Rev. B 45, 2545 (1992)], developed to explain the high field critical current (Jc) of superconducting tapes, explains the observed minimum of Jc close to H_c1 of the grains in polycrystalline materials. The quantitative agreement when fitting Jc of a well-characterized Gd₁Ba₂Cu₃O₇ ceramic shows that the minimum at H_C1 is determined by the field dependence of the magnetization of the grains.
