摘要：

Phase and structural behaviour in the SmCoO3-SmFeO3 pseudobinary system has been investigated at the ambient conditions in a whole concentration range by means of X-ray powder diffraction technique applied laboratory and synchrotron radiation sources. Series of mixed samarium cobaltites-ferrites SmCo1-xFexO3 was obtained by the solid state reaction in air at 1573 K. Formation of a continuous solid solution SmCo1-xFexO3 with orthorhombic perovskite structure (GdFeO3 type, space group Pbnm) has been revealed. Crystal structure parameters of the mixed samarium cobaltites-ferrites, as well as nominally pure SmCoO3 and SmFeO3 have been established by full profile Rietveld refinement. Based on the analysis of structural parameters, an influence of the cation substitution on the deformation of the orthorhombic perovskite structure in the SmCo1-xFexO3 series has been established.
