摘要：

Y-Ba-Cu-O thin films were prepared on yttria-stabilized zirconia (YSZ) (100), MgO (100) and SrTiO3 (100) substrates by a spray pyrolysis method. The films on YSZ, which were heated rapidly at 1020-1030-degrees-C and then exposed to argon gas until the furnace cooled to 960-970-degrees-C, showed high J(c) values of about 10(4) A cm-2 (77 K; 0 T). The films have an aligned grain structure consisting of large plate-like grains over a wide area. The melt-processing method in an argon ambient was found to be useful for the enhancement of the J(c) of thin films.
