摘要
Two kinds of methods have been used to synthesize Pb0.5ST2.5Y0.6Ca0.4Cu2O7-y samples. The synthesized sample using the first method shows superconductivity, while that using the second method exhibits a localized behavior at low temperature. Thermogravimetric analysis (TGA) and electrical transport measurements have been carried out on superconducting and nonsuperconducting samples grown under the two kinds of synthesis conditions and the effect of oxygen content on the transport and superconducting properties is discussed briefly.
