Abstract
In order to investigate the effect of the distance between the CuO2 la yer and the SrO layer, d(Cu-Sr), on the superconductivity in the Bi2Sr 2CaCu2Oy system, we have substituted Ba for Sr. Bi-(Sr, Ba)-Ca-Cu-O su perconducting thin films were prepared by the rf-magnetron sputtering method. Rietveld analysis was employed to estimate d(Cu-Sr). Samples w ith various d(Cu-Sr) were obtained by changing the post-annealing temp erature as well as the Ba concentration. T-c was found to increase wit h increasing d(Cu-Sr).
