摘要：

Crystal structures of Pb-doped BSCO superconductors, Bi2.1-xPbxSr1.9CuOywith x=0 to 0.3, are examined by transmission electron microscopy. Compounds with x from 0.05 to 0.2 exhibit satellite reflections in b*-c*electron diffraction patterns in a different manner from the x=0 compound, indicating formation of modulated structures similar to those observed in Pb-doped BSCCO superconductors. Modulation periodicity increases with increase of Pb content x. The compound with x=0.3, however, shows no satellite reflections suggesting the absence of modulation at high Pb content. © 1990 IOP Publishing Ltd.
