Synthesis and characterization of YBCO/CNT composite

Abstract

YBCO are synthesized by solid state reaction method. From XRD data, the orthorhombic structure is confirmed and measurement of resistance versus temperature is taken by four probe method. YBCO is a well-studied superconducting material has a phase transition 92 K which is above the boiling point of liquid nitrogen. CNT was added to YBCO to form a composite in order to increase its current density and observe the changes in its properties which arises due to the mixing the CNT. And phase of YBCO composite is confirmed using XRD and microstructural analysis is performed using SEM. The resistivity vs. temperature measurement is done by four probe method. Now a days, research is going on to find the mechanism of high temperature superconductivity material as BCS theory is silent about this.
