Mn-doped BiFeO 3 films were prepared by chemical solution deposition method on fluorine doped tin oxide conductive glass via spin-coating technique. XRD pattern reveals the presence of the impurity phase of Bi 2 Fe 4 O 9 in BiFeO 3 films, while no impurity phase is found in the Mn-doped thin films. XPS spectrum demonstrates the purity of prepared thin films by exhibiting the desired elements alone and it also shows that Mn-doping restrains the change of Fe3+ valency. The leakage current result shows that Mn-doping causes the change of conduction mechanism led by the change of microstructure and the restraint of Fe ions valence. BiFe 0.95 Mn 0.05 O 3 thin film has a good ferroelectric performance with high remnant polarization (P r) value of 27 μC/cm2. Mn doped BiFeO 3 films have stronger saturation magnetization than the BiFeO 3 thin films. UV vis NIR transmittance spectra depicts the optical property, which shows the optical band gap decreases with the concentration of Mn increases. • The increase of Mn doping leads to the change in surface microstructure. • Mn-doping restrains the change of Fe3+ valency. • A high remnant polarization of 27 μC/cm2 was obtained in the BiFe0.95Mn0.05O3 thin film. • Mn doped BiFeO3 thin films showed an enhanced saturation magnetization than.
