Abstract

Series of rare-earth transition element oxides Eu_0.2R_0.8FeO₃ and EuFe_0.8M_0.2O₃ ( R = rare-eartjs, M=Sc, Cr, Mn, Co) are synthesized. X-ray diffraction determinations show that these compounds possess perovskite structures. Mössbauer spectra of both ¹⁵¹Eu and ⁵⁷Fe are studied. The results show that the isomer shift of ¹⁵¹Eu in Eu_0.2R_0.8FeO₃ depends on the unit cell volume V^{1 3} of the compounds in a linear fashion. There is a certain relationship between the quadropole splitting and the lattice parameters 1 a³ in Eu_0.2R_0.8FeO₃. The hyperfine field parameters Hin of ⁵⁷Fe Mössbauer spectra are relating to R ions.
