We report a novel method of synthesizing multiferroic BiFeO 3/Pb(Zr 0:52Ti 0:48)O 3 (BFO/PZT) bilayer films based on the use of a high magnetic field. Simultaneously enhanced magnetization and electric polarization were observed at room temperature in the films annealed under an external magnetic field. Compared with the control samples annealed at zero field, the saturated magnetization and double remanent polarization were increased by a factor of 6 at room temperature. These results demonstrate that the strong magnetic annealing method is an alternative way to fabricate high-performance BiFeO 3 films.
