摘要

本文研究了在EuCoO3-EuFeO3伪二元体系中形成的混合铕钴酸盐-铁氧体的相和结构行为。揭示了具有正交钙钛矿结构(GdFeO3型，空间基团Pbnm)的连续固溶体EuCo1-xFexO3的形成。采用全剖面Rietveld细化法确定了混合铕钴酸盐-铁氧体的晶体结构参数。在结构参数分析的基础上，建立了阳离子取代对EuCo1-xFexO3系列正交钙钛矿结构变形的影响。

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 EuCoO₃-EuFeO₃ pseudo-binary system. Formation of a continuous solid solution EuCo_1-xFe_xO₃ with orthorhombic perovskite structure (GdFeO₃ 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_1-xFe_xO₃ series has been established.
