摘要：

As-grown superconducting thin films of the Bi-Sr-Ca-Cu-O system were prepared on MgO(lOO) substrates by a three-target rf magnetron sputtering system with a regulated shuttering technique. Using this system, Bi-Sr-Ca-Cu-O superconducting high-T-phase films (700 A) with a thin Bi-Sr-Cu-O semiconductor-like-phase buffer layer (70 A) were deposited on MgO (100) substrates under rigorous control of the film composition at 760°C. The superconducting transition temperature of the as-grown film was 115 K (TCoJ and 95 K (rC/ero). The surface of this film was very smooth and uniform. © 1990 IOP Publishing Ltd.
