| Abstract | Laser-induced magnetization dynamics is quantitatively investigated in a van der Waals ferromagnetic Cr2Ge2Te6 nanoflake by means of time-resolved Faraday rotation. Under ferromagnetic resonance conditions, the angular dependence of spin precession dynamics gives rise to a perpendicular magnetic anisotropy with an effective field of 125 +/- 8mT. We further determine the field dependence of the effective damping coefficient, which is dominated by the inhomogeneous broadening of magnetic anisotropy in the regime of a small magnetic field while it diminishes to an intrinsic value of 0.006 +/- 0.002 at high fields. |
