Abstract

Samples were prepared using solid state reaction method involved series of heating and grinding. Sucrose was adding during pelletization and after firing at 400°C in a box furnace, open pores were created. CaCo3 was substituted in Ba site of YBCO superconductor having a general formula Y2CaBa4Cu70y. All samples were characterized using He closed cycle four point probe to determine the critical temperature, Tc and critical current density, Jc, x-ray diffraction (XRD) for the structural properties and scanning electron microscopy (SEM) for morphology and orientation of samples. Generally, all samples displayed a normal metallic behaviour above Tc with a single transition. The values of Tc have been found to decrease towards Ca doping. From XRD, the crystal structure remains in orthorhombic where a * b ^ c for all samples. The crystal orientation becomes smaller when the pure sample was doped with Ca.
