Magnetic properties of quaternary oxides Ba 3 MRu 2 O 9 (M โซุโฌ Y, In, La, Sm, Eu, and Lu) are reported. Rietveld analyses of the X-ray di4raction data indicate that they adopt the 6Hperovskite structure and have the valence state of Ba 3 M 3ุ Ru 4.5ุ 2 O 9 . All compounds are nonmetallic at least ov

Four cuprate perovskites with the general formula A 2 CuBO 6 (A โซุโฌ Ba, Sr; B โซุโฌ W, Te) were synthesized and the structural and the magnetic properties were investigated. Among four samples, perovskite Ba 2 CuTeO 6 was formed only under high pressure. All the samples were tetragonally distorted B-s
