Fig. 2: Ultrafast photoinduced demagnetization in CrI3.
From: Coherent helicity-dependent spin-phonon oscillations in the ferromagnetic van der Waals crystal CrI3
Time-resolved polarization rotation signal under \({\sigma }_{+}\) pumping at \(T=15\,{{{{\rm{K}}}}}\), where the blue dots are experimental data and the green trace is a fit using the M3TM (see the SI for more details). The oscillatory component in the M3TM fit curve was obtained by separately fitting the oscillatory component of the experimental data with a decaying sinusoidal function. The inset shows the magnetization dynamics on shorter timescales under \({\sigma }_{+}\) (blue), \({\sigma }_{-}\) (red), and linearly polarized (green) pumping at \(T=15\,{{{{\rm{K}}}}}\).
