Thin film with a high T/sub c/ single phase was prepared on a (100)MgO substrate at a substrate temperature of about 620 /sup 0/C by coevaporation of Bi/sub 2/O/sub 3/, Sr, Ca, and Cu metal. The resistive superconducting transition with onset T/sub c/ of 80 K was observed for this film. By post-deposition annealing at 850 /sup 0/C, the high T/sub c/ phase was transformed into a low T/sub c/ phase, while films annealed at a higher temperature such as 890 /sup 0/C maintained the high T/sub c/ phase. These results indicated that the high T/sub c/ phase can exist only at the high-temperature region (approx.890 /sup 0/C) while the stable phase existing at the low-temperature region (approx.850 /sup 0/C) is the low T/sub c/ phase.
