We carried out a comparative study on the electrical and magnetodielectric properties of polycrystalline BiFeO 3 , Bi 0.9 Ca 0.1 FeO 2.95 , Bi 0.9 Ba 0.05 Ca 0.05 FeO 2.95 , and Bi 0.9 Ba 0.1 FeO 2.95 ceramics. The two dielectric anomalies, near 25 K and 281 K, are observed for BiFeO 3 . Interestingly, the anomaly near 25 K shifts towards a higher temperature above 60 K with Ca and/or Ba doping, attributed to the doping induced chemical pressure. In addition, the room temperature switchable magnetodielectric effect is witnessed for the doped BiFeO 3 compounds, due to the quadratic magnetoelectric coupling. This indicates the improved magnetoelectric coupling in BiFeO 3 with the Ca and Ba doping. This is essentially due to the enhanced magnetic ordering and reduced leakage current in BiFeO 3 after the doping.
