Abstract

Abstract The new complex oxides R2Ba1.33Th0.67Cu3O8+δ (R = La, Pr) and La0.67Ba1.33R2−xThxCu3O8+δ (R = NdGd, x = 0.5, 0.67) were synthesized. These compounds have a similar structure to the Ce-223 high-Tc oxides. The oxygen content (or δ) was varied over a wide range after annealing at high oxygen pressure (up to 90 atm). Unit cell parameters and δ values for all the new phases were determined. The resistivities of these semiconducting compounds obey the law ϱ = ϱoT−α. A single crystal of Nd2Ba1.5Th0.5Cu3−xAlxO8+δ (x = 0.3, δ = 0.8) was obtained and its structure was determined by X-ray single-crystal experiment (tetragonal system, space group I4 mmm , a = 3.9057(5) A, c = 28.569(4) A, Z = 2).
