Studies on superconductor/Nano composite of BSCCO/BiFeO3

Abstract

Superconductor BSCCO and BFO composite sample is prepared by sol-gel combustion technique using glycine as the fuel. X-ray diffraction results confirm the formation of BSCCO as major phase with some moderate amount of impurity phases. The SEM images of the sintered BSCCO and BFO composite pellet show that the samples so prepared are having distribution of grain sizes. EDXS of sample shows that the elemental composition is free from any foreign elements contamination. R-T measurement is done for all the samples. The TC for BSCCO is coming out to be around 60 K. The BFO added BSCCO samples show semiconducting behaviour as high concentration of magnetic impurity decouples the cooper pairs.
