Abstract

The visible light induced ferroelectric property for Pb(Zr0.53Ti0.47)O3/La0.67Sr0.33MnO3 (PZT/LSMO) film is investigated, and the temperature dependent ferroelectric responses is discovered. When temperature is lower than the metal–insulator transition temperature (TMI) of LSMO, both of the remanent polarization and coercive field of PZT are significantly depressed by the laser irradiation, whereas they keep unchanged once temperature rises higher than TMI. The temperature-dependent variation of ferroelectricity may be caused by photoinduced demagnetization in LSMO layer and photovoltage produced in the PZT/LSMO heterojunction. The optical modulation on ferroelectricity makes this heterojunction potential application in new ferroelectric devices.
