DC electrical Resistance measurement in composite of cuprate Superconductor

Bulk YBCO sample is prepared using solid state reaction route. Transport property of YBCO+ x NiO (x = 0.1, 0.7, 1 wt. %) is studied four probe method. Microstructural analysis is performed using scanning electron microscope and phase confirmation of YBCO powder is done by X-ray diffraction method. Data collected are computer controlled through automated programs. The transition temperature is affected on addition of NiO to YBCO. Both Tc and Tc0 decrease immensely on addition of small quantity of magnetic materia
