Abstract:
Superconducting Ba 2 YCu 3 O 7- y /Ag composite films were prepared on yttria-stabilized zirconia substrates by the dipping-pyrolysis process. Metal naphthenates were used as starting materials. Homogeneous Ba-Y-Cu-Ag solutions with (Ag/BYCO) molar ratios of 0-1.0 were spin-coated onto the substrates and pyrolyzed at 500°C. Subsequently, these prefired films were heat-treated at 750°C under a low-oxygen partial pressure (=2×10 -4 atm) followed by higher- p (O 2 ) annealing.
