摘要
We have observed a transient transmission change (Delta T) induced by photoirradiation in La0.6Sr0.4MnO3 film at room temperature. The magnitude of Delta T is enhanced with a decrease of the probe photon energy (h) over bar omega, suggesting a resonance feature to the "Drude-like" component. We interpreted the photoswitching effect in terms of the photoinduced suppression of the spin correlation in the half-metallic double-exchange system.
