Abstract

In this letter, we report the photoinduced effect modulated by different electric fields in the Pr_0.65 (Ca_0.75Sr_0.25)_0.35MnO₃/0.7PbMg_1/3Nb_2/3O₃-0.3PbTiO₃ heterostructure. The film exhibits a decrease in the resistance up to five orders of magnitude by enhancing applied electric fields, combined with an electric-field-induced insulator-to-metal transition. More interestingly, a reversible bistability arises in the photoinduced change in resistance at T < 80 K as the voltages are increased. The results can be attributed to the phase separation in manganites, which provides a prototype of photoelectric conversion for electric-field modulation of all-oxide heterostructures.
