摘要	Anisotropic carrier transports have been observed in La0.67Ca0.33MnO3 and La0.4Ca0.6MnO3 films grown on miscut MgO (001) substrates under pulsed-laser irradiations without external bias. We discussed the mechanism of the transport process under ultrafast laser irradiation in tilted manganite films. A model of anisotropic diffusion in transient photoresponse is presented. From the microstructure of La0.4Ca0.6MnO3 and its photoresponse property in different directions, we can see that the nanometer size domain orientation can modulate the photoresponse signals, indicating a new-type nanometer scale photosensitive source.
