Abstract
We report the magnetic field and temperature dependence of the critical current density {J(c)(H) and Jc(T)} flowing in a 5 lm thick sample of SmBa2Cu3O7-delta(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 J(c)alpha H-alpha with values of alpha 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/cm(2) 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. (C) 2015 Elsevier B.V. All rights reserved.
