Abstract High-T c Bi(Pb)-Sr-Ca-Cu-O thin films have been made on single-crystal MgO substrates using high-pressure dc sputtering technique. X-ray studies confirm the crystallinity and highly oriented structure withc-axis perpendicular to the substrate. By optimizing the annealing schedule the formation of the high-T c phase is stabilized. The best film exhibited superconducting transition temperature with zero-resistance temperature,T c(0), as high as 101 K. Temperature dependence ofJ c indicates the presence of Josephson-type weak links.
