The samples of Eu1–xSrxFeO3–y (x=0.0–1.0) were prepared by the solid state reaction method. Their X-ray diffraction patterns and57Fe Mössbauer spectra at room temperature were measured. It is found that Sr ions incorporate in the lattice of EuFeO3, the change of crystal structure is related to the dopant.57Fe Mössbauer spectra consist of one magnetic, one doublet and one single paramagnetic components. The Fe ions in the cubic phase are in intermediate valence state between Fe(III) and Fe(IV) and may participate in electron hopping. |
