摘要：
The extended family of Sr free Bi-2201 copper oxides has been synthesized in the Bi2+xLnyCa2-x-yCuOz (Ln=La, Pr, Nd, Sm, Eu and Gd) systems. The almost or nearly single-phase sample for each system was found to be obtained in a narrow composition region. Then, superconductivity was observed for the samples with Ln=La, Pr and Nd. Among them, the sample with Ln=Nd exhibited the highest superconducting onset at about 11 K and zero resistivity at about 9 K.
