The Electrical and Enhanced Magnetic Properties of (Ce, Co) Doped BiFeO3 Particles Synthesized Via Sol-Gel Method

Bi1-xCexFe1-yCoyO3 (BCFCO, x = 0, 0.05, 0.1, 0.15; y = 0, 0.05, 0.1, 0.15) particles were synthesized by a sol-gel method to enhance the electrical and magnetic properties of BiFeO3. The structure and morphology properties of Bi1-xCexFe1-yCoyO3 particles were analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM). XRD patterns show that the BCFCO particles are main single-phase perovskite structure with R3c space group. The enhancement of room-temperature ferromagnetism was obtained in the BCFCO particles. Obvious hysteresis loops of BCFCO were observed, which indicate ferromagnetic order. BCFCO particles exhibit reduction in leakage current density.
