Mossbauer studies of BiFeO₃ Mulitiferroic nanoparticles doped with Eu

This work presents the results of BiFeO₃ and Bi_0.9Eu_0.1FeO₃ 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 Bi_0.9Eu_0.1FeO₃ sample. And the Bi_0.9Eu_0.1FeO₃ exhibited a slight lattice distortion, observable from the results of XRD and Mossbauer spectra. We can conclude that growing of crystal homogeneity of Bi_0.9Eu_0.1FeO₃ is better than BiFeO₃.
