摘要：

The annealing effects of a "1201" superconductive lead cuprate, (Pb/Cu)SrLaCuO(y), were investigated. A single-phase ceramic sample with good superconductivity was obtained by annealing at 500-degrees-C for 24 h in nitrogen, and its fractured surface was transgranular. This sample exhibited T(c)(onset) = 38 K, T(c)(zero resistivity) = 33 K and T(C)(Meissner) = 36 K. Its volume fraction of the superconductive phase was approximately 30% at 4.2 K.
