Abstract

Abstract We report the magnetic field and temperature dependence of the critical current density {J_c(H) and J_c(T)} flowing in a 5 μm thick sample of SmBa₂Cu₃O_7-_δ (SmBCO) film. The film is a coated conductor (CC) deposited on an IBAD-MgO textured metallic template. For a range of intermediate fields, we find ^JcαH-^α with values of α between 0.44 and 0.49. These values are lower than those reported for other CC in the literature. The sample has a J_c of 13.6 MA/cm² at 5 K and self-field. Such high-J_c wires should find applications in large-scale energy applications of high-temperature superconductors. The temperature dependence of J_c at self-field and different applied fields is also analyzed.
