Effect of substitution at the barium site in YBa2Cu3O7-δ
The oxygen content in YBa2Cu3O7-δ has been varied by substitution at Ba site with Sr or K and its influence on the structural and superconducting properties has been studied. These properties are compared with that of unsubstituted YBa2Cu3O7-δ prepared by quenching. The increase in
δ value of YBa2Cu3O7-δ decreases theT c drastically, whereas in YBa2-χKχCu3O7-δ system increase in theδ value (as high as 0·92) does not affect the superconducting transition temperature, which remains above 77 K. In the YBa2-χSrχCu3O7-δ system, as Sr content increases there is marginal decrease in the oxygen content as well as in the superconducting transition temperature.
