Title: Synthesis, structure and physical properties of Ru ferrites: BaMRu{sub 5}O{sub 11} (M=Li and Cu) and BaM'{sub 2}Ru{sub 4}O{sub 11} (M'=Mn, Fe and Co)

Abstract

The synthesis, structure, and physical properties of five R-type Ru ferrites with chemical formula BaMRu{sub 5}O{sub 11} (M=Li and Cu) and BaM'{sub 2}Ru{sub 4}O{sub 11} (M'=Mn, Fe and Co) are reported. All the ferrites crystallize in space group P6{sub 3} /mmc and consist of layers of edge sharing octahedra interconnected by pairs of face sharing octahedra and isolated trigonal bipyramids. For M=Li and Cu, the ferrites are paramagnetic metals with the M atoms found on the trigonal bipyramid sites exclusively. For M'=Mn, Fe and Co, the ferrites are soft ferromagnetic metals. For M'=Mn, the Mn atoms are mixed randomly with Ru atoms on different sites. The magnetic structure for BaMn{sub 2}Ru{sub 4}O{sub 11} is reported.
