Superconducting Bi-Pb-Sr-Ca-Cu-O films doped with Sb have been fabricated on MgO single-crystal substrates without post-annealing, using pulsed excimer laser deposition. Deposition at 800 {degree}C in 0.2 Torr oxygen environment from a target doped with Sb yielded as-deposited superconducting films with zero resistance at 70 K. X-ray diffraction data show the films are {ital c}-axis oriented 2212 phase material. Scanning electron micrographs indicate that doping with Sb enhances grain growth. These results demonstrate that Sb acts to stabilize the 2212 phase in the as-deposited films.
