Abstract

Series of rare-earth transition element oxides Eu0.2R0.8FeO3 and EuFe0.8M0.2O3 ( 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 Eu0.2R0.8FeO3 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 Eu0.2R0.8FeO3. The hyperfine field parameters Hin of 57Fe Mössbauer spectra are relating to R ions.
