DC Electrical Resistivity Studies in bulk YBCO/Ag composites

Abstract

Bulk YBCO sample is prepared using chemical route method. Ag is used as composite because of its advantageous properties. The samples are characterized by the vs T measurement performed by FOUR PROBE METHOD. Data are collected by automatic programming and analyzed for the behaviour. SEM is done to study the grain morphology. It is found that by increase in the weight percentage of Ag in the composite sample the transition temperature decreases slightly. From SEM images, it is observed that the grains become smaller in sizes as compared to prestine.
