Structural behavior in the EuCoO3-EuFeO3 System

The work deals with the study of the phase and structural behaviour of mixed europium cobaltites-ferrites formed in the EuCoO

with orthorhombic perovskite structure (GdFeO

type, space group Pbnm) has been revealed. Crystal structure parameters of the mixed europium cobaltites-ferrites have been established by the 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 EuCo
