This report reveals the room temperature magnetodielectric effect of polycrystalline BiFe0.8Mn0.2O3 ceramics. Structural analysis shows that the additional phases of BiFe0.8Mn0.2O3 are suppressed and compared with bare BiFeO3. The difference in dissociation energies between Mn–O and Bi–O bonds traps...
