Bi1-xCexFe1-yMnyO3 samples (0 <= x <= 0.10 and 0 <= y <= 0.05) were synthesized by the sol gel technique to investigate the effect of Ce and Mn doping on the structural, magnetic and electrical properties of multiferroic BiFeO3 (BFO). It is observed that Ce Mn doping induces structural changes in BFO and also decreases the secondary phases noticeably. Frequency dependent dielectric properties of pure and doped BFO samples were measured from 300 K to 675 K in the frequency range of 1 KHz-1 MHz. Enhanced ferromagnetism and improved ferroelectric properties were observed which may be correlated with the structural transformation and grain morphology. As Ce concentration increased in BFO, the leakage current density decreased gradually. We have observed here exciting properties in doped bismuth ferrites which provide the possibility to create new functional material.
