%X The doped manganites Pr2/3Sr1/3MnO3 (PSMO)film was prepared by the pulsed laser deposition method. The spin transport properties of the film induced by the magnetic field, laser and the current field were investigated. In ferromagnetic metallic state, the laser irradiation results in the increase of the resistance, which is attributed to the photoinduced demagnetization effect. But the magnetic field and the current induce the resistance decrease because the magnetic field and the current align the magnetic moments of the nearest Mn ions and enhance the double-exchange effect. In the paramagnetic insulating phase, the three external fields induce the decrease in the resistance, which is due to the field-induced delocalization of the small polarons.
