Notes:
YBa2Cu3O7−x thin films were prepared on (100)yttria-stabilized zirconia (YSZ) by a spray pyrolysis method. The films were fired rapidly at 1000–1020 °C in flowing helium atmosphere and then annealed in oxygen. These melt-textured thin films had the aligned grain structure consisting of large, platelike grains over a wide area. The films thus formed showed relatively high critical current density Jc more than 4000 A/cm2, and the best Jc of the film fired at 1010 °C was 4800 A/cm2 at 77 K in zero magnetic field. The melt-textured growth processing was found to be more useful for the enhancement of the Jc value of thin films than the conventional sintering method.
