Investigate Oxygen Content in YBa₂Cu₃O_7-_δ Superconductors

Abstract:

The YBa₂Cu₃O_7-_δ(Y123) compounds were synthesized by solid state reaction method. The home-made four-probes apparatus was used for the resistivity measurement. The highest T_c is 91.95 K in sample C and sample A has lowest T_conset at 89.85 K. The crystal structure properties and oxygen content were characterized by powder X-ray diffraction using CuK_α radiation (λ=1.5406 Å). The Pmmm and Pnma space group corresponding on the superconducting phase and the non-superconducting phase. The atomic position of samples were consisted of various element atom. The longer time of oxygen-doping, the increase the critical temperature , superconducting phase and c lattice parameters.
