Abstract

The YBa2Cu3(>7-8(Y123) compounds were synthesized by solid state reaction method. The home-made four-probes apparatus was used for the resistivity measurement. The highest Tc is 91.95 K in sample c and sample A has lowest Tc onset at 89.85 K. The crystal structure properties and oxygen content were characterized by powder X-ray diffraction using CuKa radiation (X= 1.5406A). The Pmmm and Pnma space group corresponding on the superconducting phase and the non-superconducting phase. The atomic position of samples was consisted of various element atoms. The longer time of oxygen-doping, the increase the critical temperature, superconducting phase and c lattice parameters.
