摘要

The compound SrLaMnRuO6 has been prepared andthe crystallographic phase transition from orthorhombic phase withthe space group Pnma (GdFeO3-type) to rhombohedral phase withR3c was found near 500 K by high temperature X-raydiffractometry and thermal analysis. The crystal structure ofSrLaMnRuO6 has been refined by the Rietveld method with X-raypowder diffraction data between room temperature and 773 K.
