High-quality YBa/sub 2/Cu/sub 3/O/sub 7/ films supported on yttrium stabilized cubic zirconia were made by simultaneous reactive magnetron sputtering using yttrium, barium, and copper metal targets. Superconductivity onsets of 92 K with transition widths of 1.5 K (10%--90%) have been achieved on yttrium stabilized cubic zirconia substrates. Various aspects of the deposition processes are described and the effect of deposition parameters and post-annealing on thin-film stoichiometry, structure, and superconducting properties is discussed.
