- 論文の詳細を見る
Effect of oxygen deficiency on crystal structure and superconductivity of Ba_2YCu_3O_<7-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℃ and maximum oxygen deficiency, δ=0.7 was observed for the tetragonal phase.
