摘要：

Single-phase samples of the new superconductor (Pb, Cu)(Sr, Ba)2(Y, Ca)Cu2Oz (1212 phase) were prepared at 920°C in air, and the solubility limits of Pb, Ba and Ca in the 1212 phase were studied. For three single-phase samples and one almost-single-phase sample, the Tc's were determined by the ac susceptibility. It is found that the Tc depends on the oxygen and Ca contents of the 1212 phase. © 1990 The Japan Society of Applied Physics.
