The electronic structure as well as the photoinduced effect were investigated in an antiferomagnetic LaMnO3 film. We found characteristic spin-dependent absorption bands at [approximate]1.6 eV and ~3 eV, and ascribed them to the d–d transitions into the adjacent Mn3+ sites with the parallel and antiparallel spins, respectively. We further observed that the photoexcitation of the down-spin d electrons significantly influences these d-d bands, and ascribed the behavior to the photoinduced disorder of the Mn3+ spins
