· J. Solid State Chem.; (United States)
A new superconductor was isolated and characterized by X-ray diffraction and electron microscopy. This oxide crystallizes in tetragonal system (P4/mmm) with the following parameters: a = 3.833 A and c = 12.680 A. A structural model was established from X-ray powder data. The structure is a new member of the family (AO)/sub n/(A'CuO/sub 3-y)/sub n'/ (A = Tl, Ba and A' = Ba, Ca) with n = 2 and n' = 2. It can be described as the intergrowth of double (AO layers, rock salt-type, with double oxygen-deficient perovskite layers involving CuO/sub 5/ pyramids. The optimization of the thermal treatment and the importance of oxygen content are discussed.
