Abstract

In order to study the relation between the oxygen content and superconductivity samples of Bi₂Sr₂Ca_1-xK_xCu₂O_y (x=0, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0) were prepared and treated under different conditions. It was found that the superconducting properties are sensitive to the oxygen concentration and the T_c,zero of Bi₂Sr₂Ca_1-xK_xCu₂O_y can be shifted over a range of about 22 K by the changing oxygen concentration; no structural difference induced by oxygen were observed. The change in superconducting properties may be the result of a change in Cu average valence state. In addition, the change in superconducting phase with K⁺ concentration is also studied.
