NEW FAMILY OF SUPERCONDUCTING COPPER OXIDES - GASR2LN1-XCAXCU2O7
We have prepared a new copper oxide, GaSr2Ln1-xCaxCu2O7 (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 Cu...
