Abstract

The effect of Mn doping on crystal structure, electric, magnetic and optical properties of BiFeO₃ thin films prepared via the sol-gel process on indium tin oxide/glass substrates was studied. X-ray diffraction analysis indicated that Mn-doped BiFeO₃ thin films presented single tetragonal structure with P4mm symmetry. Compared with the pure BiFeO₃ film, the resistivity was found to increase while leakage current density and optical band gap decreased in low Mn content (?7.5%) doped BiFeO₃ system. An evident magnetic hysteresis loop was observed for all the thin films at room temperature and Mn-doped BiFeO₃ films showed a larger saturated magnetization than pure BiFeO₃ film.
