Abstract

We have prepared a new copper oxide, GaSr₂Ln_1-xCa_xCu₂O₇ (0 ≤ x ≤ 0.4), that becomes superconducting a high-pressure oxygen annealing. While the undoped parent compound, x = 0, does not show three-dimensional magnetic order above 4 K, probably due to the presennce of the thick ionic separating the CuO₂ layers, superconductivity with a high-T_c (∼70 K) is possible for the doped compositions.
