Mossbauer studies of BiFeO3 Mulitiferroic nanoparticles doped with Eu

This work presents the results of BiFeO3 and Bi0.9Eu0.1FeO3 multiferroic materials, synthesized via a simple solid-phase reaction method. Both of the synthesized materials were in the rhombohedral R3c structure as observed by X-ray diffraction (XRD). The presence of a doublet along with a sextet in Mossbauer spectra indicates an impurity phase (Bi2Fe4O9). The presence of Fe2+ ions are confirmed from Mossbauer spectroscopy study in the Bi0.9Eu0.1FeO3 sample. And the Bi0.9Eu0.1FeO3 exhibited a slight lattice distortion, observable from the results of XRD and Mossbauer spectra. We can conclude that growing of crystal homogeneity of Bi0.9Eu0.1FeO3 is better than BiFeO3.
