Superconducting Bi-Sr-Ca-Cu-O films have been fabricated by RF magnetron sputtering using single mixed Bi/sub 2/O/sub 3/-SrF/sub 2/-CaF/sub 2/-CuO targets. Uniform, reproducible films were formed on SrTiO/sub 3/ substrates with zero resistance as high as 78 K. Grain morphology and orientation were affected by annealing temperature and the F content of the films. The final films showed excellent environmental and mechanical stability.
