Abstract

Bi-Sr-Ca-Cu-O (BSCCO) films were prepared on MgO(100) single-crystal substrates at 770ŶC by chemical vapor deposition using ॆ-diketone metal chelates of Sr, Ca and Cu and Bi-triethoxide. The films were Bi₂(Sr, Ca)₃Cu₂O_x (c=30 Ɨ) with c-axis orientation. The films showed superconducting transition onset at 90 K with zero resistivity at 74 K. The formation of films having high-T_c phase (Bi₂(Sr, Ca)₄Cu₃O_x, c=37 Ɨ) was achieved when the films were annealed at 890ŶC for 5 h under 760 Torr of oxygen. The resistivity of the annealed films began to drop sharply at around 110 K and reached zero at 77 K.
