Fig. 4.
Time dependence of Bragg peaks for 1.0% electronic excitation. Simulated Bragg peaks [(002)R, (−2 − 23)R, (−131)M1, (−1 − 13)M1, (112)M1, (−120)M1] as a function of time are obtained through the structure factors (see Eq. 3). Red diamonds and yellow circles show the relative changes in the R-phase peak and M1-phase peak measured by X-ray diffraction experiments (14).
