Synthesis and Characterization of YBa2Cu3O7-x Superconductor

Abstract

We have synthesized YBCO superconductor via solid state reaction route and characterized it with XRD, R vs. T and I-V measurements. From XRD graph we have identifying the phase formation of our sample and from R vs. T measurement we found the onset of superconductive transition occur at (TCO) 92.17 K; which also gives an extra supporting data towards the phase formation. We also subjected our sample for I-V characterization at different temperatures (30, 35, 45, 50 K) through four probe method and able to find out the critical current density at the subsequent temperatures and found a decrement of critical current density with increment of temperature
