英文摘要We synthesized (Pb,Cd)Sr-2(Y,Ca)Cu2O7+x phase superconductor. After substitution of ph with Bi, the BiCd1212 phase shows no superconductivity. Although previous EXAFS study has shown the local structure environment of the Cu is similar in both compounds, EXAFS results of Bi and Pb here demonstrate that sigma(2) of Pb-Oin-plane is larger than that of Bi-Oin-plane, whereas sigma(2) of Pb-O-apical is smaller than that of Bi-O-apical. The Sr shell features are also different. It appeared that superconductivity needs some disorder in carrier reservoir layer, which is due to the substitutional defect caused by different ionic radii.
