Systematics in the superconducting behaviour of Ln 2−xSr x(Ba x)CuO 4, La 2−xSr x−yBa y(Ca y)CuO 4, (La 1−xLn x) 2−ySr y(Ba y)CuO 4 with Ln = Pr, Nd or Y and related systems are presented. The role of oxygen stoichiometry and lattice parameters of these mixed valent copper oxides is indicated. These high T c superconducting oxides exhibit high-temperature resistivities in the borderline of the metal-nonmetal transition.
