Abstract

Superconducting films of bismuth strontium calcium copper oxides were prepared by chemical vapor deposition at 910°C and 1 Torr on MgO substrate using a bismuth alkoxide and β-diketonate chelates of Sr, Ca and Cu as source materials. In the film with T_c(zero) of 78 K, the predominant phase was Bi₂(Sr, Ca)₃Cu₂O_x with the c-axis perpendicular to the infstrate.
