摘要：

Excellent critical current behavior at 77 K in magnetic fields up to 14 T has been obtained for Ba2YCu3O7-y (BYCO)-Ag films prepared by dipping-pyrolysis process. The films were epitaxially grown on SrTiO3(100) substrates using a two-step annealing (low-p(O2)/pure O2) method at 770-degrees-C. The best values of critical current density at 77 K under a 2-muV/cm criterion were 1.2 x 10(6) A/cm2 in a self field and 1.0 X 10(5) and 3.8 X 10(4) A/cm2 at 8 T and 14 T, respectively, when the field was applied parallel to the a-b plane.
