摘要：

A detailed study has been carried out of the successful fabrication of high current capacity, thick films of YBCO on yttria-stabilized zirconia substrates. This has involved the optimization of a number of processing parameters including material composition, processing temperatures and times, ink additives and so on. As a result of this work, thick films have been obtained with thicknesses of as little as 7-mu, which are superconducting with T(c) = 91.5 K and have critical current densities at 77 K of almost 3 x 10(3) Acm-2. This current decreased rapidly with increasing magnetic field strength, reaching an almost constant value of 100-200 Acm-2 at 0.4 T.
