Image of FIG. 1.
FIG. 1.

(Color online) (a) XRD patterns and (b) the UV-Vis absorption spectrum for hexagonal YMnO3 film. The inset illustrates the 3d orbit splitting of the Mn3+ ion in trigonal bipyramid environment.

Image of FIG. 2.
FIG. 2.

(Color online) Relaxation curves of the relative transmittance change ΔT/T of YMnO3 film at two excitation energies: (a) 1.7 eV and (b) 2.0 eV. The temperatures marked in the figure are the steady-state temperatures of sample. ΔT/T curves are shifted along the vertical axis for clarity. The black solid lines show the fitting results by Eq. (1).

Image of FIG. 3.
FIG. 3.

(Color online) The temperature dependences of fitting parameters given by Eq. (1): (a) time constants , (b) amplitudes of slow component B, and (c) background signal for two excited energies, 1.7 eV and 2.0 eV. Vertical broken lines correspond to Tc = 120 K.
