DC Electrical Resistivity Studies in YBCO/BZT Composites

Das, Rasmita (2011) DC Electrical Resistivity Studies in YBCO/BZT Composites. MSc thesis.



Bulk YBCO sample is prepared using chemical route method. BZT is used as composite because its properties can be utilized for pinning effect that enhances critical current density. The sample is characterized by the ρ vs. T measurement performed by FOUR PROBE METHOD. Data are collected by computer controlled programming and analyzed for different behaviors. SEM is done to study the grain morphology. It is found that by increase in the weight percentage of BZT in the sample, the transition temperature decreases and from the SEM images, the grains become elongated in sizes. This elongation is advantageous for pinning purpose
