(a) Magnetic field dependence of the total critical current, Ic−w(H), for 250 nm pristine YBCO (black line) and 350 nm YBCO-20 mol% BHO (5 nm) pn-nanocomposite (blue line) measured at 5 K and 77 K (SQUID), (b) temperature dependence of the critical current density Jc (T) measured at 7 T for the pristine YBCO and 350 nm YBCO-20 mol% BHO (5 nm) pn-nanocomposite. The curves have been fitted with two contributions (strong and weak pinning). The 250 nm pristine YBCO film is processed by conventional thermal treatment and the 350 nm pn-nanocomposite following the flash heating process.
