(a) External field-dependent magnetization dynamics of 10-nm Co₂Fe_0.7Mn_0.3Al film (open dot) under 12.5 mJ · cm − 2 , and their fittings (solid line). The schematic measurement configuration is shown in the inset. (b) The frequency (black solid dot) and decay time (black open dot) were extracted from the fitting and FFT (red solid dot), respectively. The inset shows FFT spectrum.
