Structural and magnetic properties of Cr doped BiFeO3 multiferroic nanoparticles

摘要: BiFeO3 (BFO) and 5% Cr doped BFO nanoparticles were synthesized by a facile sol-gel route. Both the samples were characterized by XRD, VSM (MT) and Mössbauer spectroscopy. XRD revealed the phase pure formation of samples and the crystallite sizes were well below the periodic order of spiral spin structure of BFO. 57Fe Mössbauer spectroscopy confirmed the presence of only Fe3+ in the samples. BFO and Cr-doped BFO were found to be weakly ferromagnetic in nature.
