Abstract

Superconducting oxide related compounds in the PrSrCuO system under 1 atm of O₂ at 1080°C were investigated. Pr_2-xSr_1+xCu₂O_6-δ (x=0.15, 0.85 ≤ x ≤ 1.00), Pr_2-ySr_yCuO_4-δ (y=0.4, 1.43), and Pr₈Sr₇Cu₂O_x were prepared in the system of PrSrCuO at 1080°C under 1atm of O₂. The crystal structures of Pr_2-xSr_1+xCu₂O_6-δ were 2126-type (x=0.15) and superstructure (a × 3a × c) of 2126-type (0.85 ≤ x ≤ 1.00). Pr_1.6Sr_0.4CuO₄ had the T*-type structure. The structure of Pr_0.57Sr_1.43CuO_4-δ was related to the K₂NiF₄-type (T-type) structure. The X-ray powder diffraction pattern of Pr₈Sr₇Cu₂O_x was indexed with hexagonal lattice parameters of a=10.164 and c=3.623 A ̊. Orthorhombic compounds of Pr_3.8Sr_3.2O_x and PrSr₂O_x were prepared in the Pr-Sr-O system. All of these compounds showed semiconducting behavier.
