Abstract
We examined the effect of light illumination on the magneto-electric behavior of the BiFeO3 thin film which deposited onto BaTiO3 piezoelectric layer by the aid of pulsed laser deposition technique. The ferroelectric polarization of the sample has been measured under electric field bias and illumination of different power of laser diode with a center wavelength of 406nm in the presence of magnetic field. The photo-magnetic assisted ferroelectric polarization of the sample has been observed when the sample illuminated with light under magnetic field. Our results show the linear dependence of this answer with the power of light. This effect can possibly open a research development in photoassisted ferroelectric behavior properties for next generation devices.
