Robust critical current density in applied magnetic fields in 5 $\mu$m thick, SmBa$_{2}$Cu$_{3}$O$_{7-\delta}$ based superconducting wires*

We report the magnetic field and temperature dependence of the critical current density \textbraceleft $J_{c} (H)$ and$J_{c} (T)$\textbraceright flowing in a 5 $\mu$m thick sample of SmBa$_{2}$Cu$_{3}$O$_{7-\delta}$ (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 also has higher $J_{c}$ values when compared with other wires with similar thicknesses. 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.
