Abstract

Structural, spectroscopic and magnetic properties of pure BiFeO₃ and Mn-doping BiFeO₃ nanoparticles synthesized by precipitation method were studied. The synthesized samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (SEM), X-ray absorption near edge structure spectroscopy (XANES) and vibrating sample magnetometry (VSM). No secondary phase or metallic Mn clusters can be detected for pure BiFeO₃ and those samples with Mn content up to 10%. The results from VSM reveal that the pure BiFeO₃ and Mn-doping BiFeO₃ samples exhibit antiferromagnetic behavior at room temperature.
