Paper Abstract

A high current density YBa2Cu3O7-x (YBCO) superconducting thick film on a flexible NiCr alloy substrate tape with ZrO2 + 10 percent Y2O3 (YSZ) as buffer layer was prepared by pulsed laser deposition. The buffer layer YSZ of thickness 0.3 micrometers was formed on the NiCr alloy substrate tape of length 6.0 cm by ion-assisted pulsed laser deposition. The YBCO superconducting thick film with thickness 1.5 micrometers was deposited on the YSZ/NiCr alloy substrate tape by a KrF laser. The x-ray diffraction pattern indicates that the YBCO superconducting thick film is with strongly C-axis oriented. The critical current densities versus temperature and magnetic field were measured by standard four-point probe method, the values of critical current density and the critical temperature of the YBCO/YSZ/NiCr alloy superconducting tape are 8.75 X 104 A/cm2 and 88.7 K, respectively.
