(a) Temperature dependence dephasing time of the oscillation component in at various wavelengths of HoMnO3. Inset: the normalized dephasing time as a function of temperatures at various wavelengths [38]. Figures were reproduced with permission from Shih et al. [38]. (b) Temperature dependence of dephasing times: red squares for acoustic phonons, black circles for optical phonons, and blue triangles for electronic relaxation time [37]. Figures were reproduced with permission from Jang et al. [37].
