Abstract

YBa2(Cu1-yCoy)3O7-δ superconductors with y = 0.00 ∼0.06 are synthesized. The content of oxygen increases with increase in cobalt content, while the oxidation of copper is almost independent of cobalt concentration. The orthorhombic-to-tetragonal transition occurs in the range of 0.028< y< 0.038 according to neutron powder diffraction studies on samples with y = 0.03. Structural refinements for X-ray and neutron diffraction data show that there is an orthorhombic phase with y≤0.02 and a tetragonal phase with y>0.04. There is an orthorhombic and a tetragonal phase coexisting in a sample withY = 0.03. The content of cobalt in the tetragonal phase (0.038) is larger than that in the orthorhombic one (0.028). It seems that the structure of YBa2Cu|1-y CoyO x is unstable near the point of phase transition.
