摘要：

New perovskite compounds Sr(Li1/4Ru3/4)O3, Sr(Na1/4Ru3/4)O3, (Sr1/2La1/2)(Mg1/4Ru3/4)O3 and (Sr7/8La1/8)(Mg1/4Ru3/4)O3 have been prepared. The crystal structures of these compounds were determined by powder X-ray Rietveld analysis. The crystal structure of these compounds was orthorhombic with space group Pnma. Electrical resistivity and magnetic susceptibility were measured for the samples with the nominal ruthenium valences from 4.0+ to 5.0+. In this study, the crystal structure, electrical conductivity and magnetic properties of the new ruthenium perovskite compounds are discussed.
