Synthesis and characterization of bismuth ferrite particles using a nano-agitator bead mill

Bismuth ferrite (BiFeO3) nanocomposites were synthesized using a novel nano-agitator bead milling method followed by calcination. oxide and iron nanoparticles mixed in stoichiometric ratio milled for 3 h calcined at 650 °C air. X-ray diffraction with Rietveld refinement, scanning electron microscopy, transmission microscopy techniques used to elucidate the structure of BiFeO3. The particle diameter was found be ∼17 nm. Magnetic electrical measurements performed, these results compared those similar methods. Mostly, BiFeO3 obtained minor secondary phase formation. resulting powder weakly ferromagnetic remnant magnetization 0.078 emu/g. This can attributed residual strain defects introduced during process. Electrical testing revealed high leakage current density that is typical undoped bismuth ferrite.
