| Abstract: | The superconductivity, magnetoresistance and transport property of Bi_3PbSr_3Ca_3Cu_4O, superconductor have been measured. By microstructure analysis, we studied the granular superconductivity of this oxide superconductor. This experiment let us observe the effect of grain boundary on trasport property. In addition, above results have been analysed. |
