【 摘 要 】

This paper describes the synthesis of multiferroic BiFeO3 ceramics was prepared by solid state reaction and high energy ball milling method. The structural studies was carried out by using an X-ray diffraction pattern and demonstrated that the BiFeO3 ceramic crystallizes in a rhombhohedral perovskite phase. The ferroelectric hystersis loop measured at room temperature demonstrates a lossy loop with unsaturated behavior and symbolize a partial reversal of polarization. A dielectric constant with temperature measurement for BiFeO3 ceramic represents an anomaly around 350°C for all frequencies and intimately associated with antiferromagnetic to paramagnetic phase transition (TN) of BiFeO3.
