中文摘要	A series of new superconductors Sr2-xBaxCuO3+delta (x <= 0.6) were prepared under high pressure high temperature. The superconductors crystallize into K2NiF4-type structure of I4/mmm space group similar to the classical La2CuO4 but with partially occupied apical oxygen. It is found that T-c of this barium doped Sr2CuO3+delta superconductor is associated with the ratio of A-site cation substitution while keeping at optimal carrier doping level. The superconducting transition temperature with T-c(max) = 98 K which represents the record high T-c in the single-layer copper oxide superconductors was achieved in this material.
