Polycrystalline BiFeO3 (BFO), Nd-doped (BNF), Mn-doped (BFM), and (Nd,Mn)-codoped BiFeO3 (BNFM) thin films were fabricated on Pt/SrTiO3(100) substrate by pulsed laser deposition. According to the X-ray diffraction analysis and atomic force microscope observation, suppression of impurity phases and improvement of surface morphology were realized in the BNFM film. In the BNFM film, the leakage current was reduced compared with BFO, BNF, and BFM films, and $P$--$E$ hysteresis curves were observed with measurement frequency of 100 Hz at room temperature. The remanent polarization and coercive field were approximately 100 μC/cm2 and 250 kV/cm, respectively.
