Magnetic properties of a quaternary oxide Ba 3 NdRu 2 O 9 are reported. This compound adopts the 6H-perovskite structure with space group P6 3 /mmc, in which the cation sites within the face-sharing octahedra are occupied by ruthenium ions and those within the corner-sharing octahedra are occupied b
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
B โซุโฌ Nb and B\* โซุโฌ Ca were synthesized by a conventional calcination process, as well as by the molten salt method. The former consists of calcining appropriate mixtures of oxide or carbonate precursors in air at elevated temperatures (&12503 3C). The latter method consists of adding appropriate m
