Abstract

The critical current densities J_c-w(H) per unit width of the tape were measured at 75K in applied magnetic fields H on a 3νm-thick YBa₂Cu₃O₇ film on a metallic substrate fabricated using the BaF₂ process. J_c-w(H) was the highest reported for YBa₂Cu₃O₇ conductors with H perpendicular to the tape, and was independent of the angle between H and the tape plane for μ₀H≤3T. The film did not contain artificial flux-pinning centres, implying the existence of a strong isotropic-pinning centre in undoped YBa₂Cu₃O₇ films, thus opening up unexplored avenues for improving performance of coated conductors.
