摘要：

Superconducting YBa2Cu3O7-y (YBCO) films having a thickness of 1-mu-m were prepared on SrTiO3(100) and MgO(100) by the dipping-pyrolysis process using a low-p(O2) annealing method. Heat-treatment conditions were varied along the upper limit of the stability region of the YBCO phase. Films on SrTiO3(100) exhibited strong c-axis orientation with sharp rocking curves (FWHM = 0.8-degrees). The highest T(c,zero) of 87 K was obtained for the film heat-treated at 750-degrees-C. On the other hand, films on MgO(100) showed broader rocking curves and their T(c)'s remained lower. Moreover, Ag addition was found to enhance the T(c) values (T(c,zero) = 91 K) of films on SrTiO3 beat-treated at 750-degrees-C.
