Polycrystalline Bi_1-xMn_xFeO₃(x=0.0, 0.1, 0.2, 0.3) were synthesized using sol-gel method to study the structural and dielectrical properties. Raman analysis confirmed the rhombohedral structure (3Rc) in all the prepared samples. Raman measurements were carried in both parallel and crossed polarization configuration. In dielectric studies, dielectric constant (both ε’ and ε”) and dielectric loss were observed to decrease with increasing frequency (100Hz to 1MHz) at room temperature. Dielectric constant and dielectric loss increases with increases in temperature. Leakage current density was observed to increase with increasing Mn doping concentration.
