Abstract

Effect of oxygen deficiency on crystal structure and superconductivity of Ba2YCu3O7-δ was studied by annealing and quenching experiments. With increasing oxygen deficiency superconductivity was suppressed remarkably while axial ratio, a 0/b 0 in the orthorhombic phase approached to unity and c 0 value increased. Structural transformation from orthorhombic to tetragonal lattice took place in the temperature range, 950∼980°C and maximum oxygen deficiency, δ=0.7 was observed for the tetragonal phase.
