The X-ray diffraction pattern for Bi0.9Eu0.1FeO3 was analyzed by the Rietveld refinement using FULLPROF computer program. The crystals were determined to be a rhombohedrally distorted perovskite-like structure with a space group of R3c. SQUID and VSM measurements showed the antiferromagnetic behavior with Néel temperature (T N) of 638 and 633K for x=0.1 and 0.2, respectively. A least-squares fitting program was used to determine the Mössbauer parameters by assuming Lorentzian line shapes. The valence state of Fe ion is Fe3+ relative to the Fe metal, according to the isomer shift (δ) value = 0.39mm/s at 4.2K. In determining the inter-atomic binding force in Bi0.9Eu0.1FeO3, the Debye temperature was 486 and 477K, respectively.
