Abstract

The visible light induced ferroelectric property for Pb(Zr_0.53Ti_0.47)O₃/La_0.67Sr_0.33MnO₃ (PZT/LSMO) film is investigated, and the temperature dependent ferroelectric responses is discovered. When temperature is lower than the metal–insulator transition temperature (T_MI) 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 T_MI. 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.
