摘要：

The superconducting oxide in the Sr-Ca-Y-Pb-Cu-O system was identified and prepared as a single phase. The compound examined has a tetragonal cell with a=3.815 Å and c=11.85 Å. The Tcwas 17 K for the sample quenched from 860°C to 77 K, and below 4.2 K for the sample annealed in air at 400°C. © 1990 IOP Publishing Ltd.
