The solid state solutions of europium transition element oxides Eu (Fe_0.8M_0.2)O₃ (M=Sc, Cr, Mn, Co) are synthesized. The X-ray diffraction of the compound shows that all the compounds possess the perovskite structures. Both the ¹⁵¹Eu Mössbauer spectra and the ⁵⁷Fe Mössbauer spectra are measured. The hyperfine magnetic field and non- axisymmetric electric field gradient are observed in the ¹⁵¹Eu Mössbauer spectrum. The ⁵⁷Fe Mössbauer spectrum shows that there are four components of hyperfine fields corresponding to four kinds of different neighbours of the Fe ion.
