- Magnetoelectric effect has been studied in films of BiFeO3 with particle sizes in the range, 12 to 92nm deposited by spray pyrolysis method. The field emission scanning electron microscopy images show that the films were uniform, dense and of near spherically shaped nano-particles. The ferroelectric loops were studied in the presence of magnetic field and about 30% increase in the remanent polarization was obtained. The enhanced polarization was observed above some critical value of the applied field which is attributed to the suppression of cycloidal spin structure. A large coupling between ferromagnetic and ferroelectric order parameters has been found at room temperature. It has been attributed to the large ferroelastic domains and suppression of the cycloid spin structure. ► BiFeO3 films deposited by spray pyrolysis method at low temperature ► Improved ferroelectric and ferromagnetic properties were obtained ► A strong magnetoelectric coupling was observed.
