| Abstract: | The polycrystalline fine powder (~60 nm) of Bi₀․₉₀La₀․₁₀ (Fe₁₋xMnx)O₃ (x= 0, 0.05, 0.10 and 0.20) have been synthesized by mechanical activation and mixed oxide methods. Preliminary structural analysis using X-ray diffraction exhibits formation of the single-phase compound in a hexagonal (distorted perovskites system). Detailed dielectric studies as a function of temperature show that dielectric constant of BFO (BiFeO₃), and also tanδ increase significantly on increasing Mn content in BiLa(FeMn)O₃ system. Impedance analysis of the system provides many interesting results. |
