Abstract

Effects of Pb-substitution on the electrical and magnetic properties and the microstructure of the Bi-based cuprate superconductors, especially Bi-2212 (Bi2Sr2CaCu2O8+δ) polycrystalline phase, have been studied by XRD, SEM, TEM and magnetic measurements. The larger hysteresis loops of the Pb-substituted Bi-2212 phase in M-H curves were observed in comparison with the Pb-free Bi-2212 phase. The disorder of the structural modulation and the formation of micro-twins were found in the Pb-doped Bi-2212 phase by TEM observations. These results were caused by inhomogeneity of Pb concentration in the crystal.
