摘要	We report the transient laser-induced anomalous photovoltaic effect in the La0.67Ca0.33MnO3 film grown on miscut LaSrAlO4 (001) substrate under 248 nm pulsed laser irradiation at ambient temperature without any applied bias. A photovoltaic pulse signal was observed when the La0.67Ca0.33MnO3 film was irradiated directly, and the signal polarity was reversed when the sample was irradiated through the LaSrAlO4 substrate, while the signal recorded between the two electrodes on the surface of LaSrAlO4 was not reversed when the sample was irradiated through La0.67Ca0.33MnO3 film rather than at the surface of LaSrAlO4. The switchable signal polarity provides a potential application of miscut manganite films as optical components. A possible mechanism is introduced to explain the experiment results.
