Abstract

Cuprates with an Anion-Deficient Perovskite Structure in the La 2 O 3 -SrO-CuO-CoO System: Synthesis and Study.-The effect of substitution of copper by cobalt on the stability range of mixed oxides La 8−x SrxCu 8−y CoyO 20 having a tetragonal oxygen-deficient perovskite type structure is studied. The unit cell parameters of these solid solutions, synthesized by solid state reactions of stoichiometric amounts of La 2 O 3 , CuO, CoO and SrCO 3 , and their electric properties are determined. Heating a sample of n…
