"We investigate the photo-induced carrier dynamics and spin-lattice interaction in hexagonal YMnO(3) film by the temperature-dependent femtosecond pump-probe spectroscopy. The spin-lattice interaction is identified from the slow component of the transient transmittance change with the excitation energies tuned to 1.7 eV and 2.0 eV, which are close to Mn(3+) ions d((xz),(yz)) d((z2)) and d((x2-y2),(xy)) d((z2)) transition, respectively. Temperature dependences of the spin-lattice relaxation parameters demonstrate that the spin-lattice interaction is strongly connected with the d-d transition within Mn(3+) ions and enhanced by spin ordering.
