Abstract

A high current density YBa₂Cu₃O_7-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.
