Fig. 4: Schematic illustrations of the feromagnetic resonance modulations scaling forms.

The frequency and temperature dependence of the enhanced Gilbert damping coefficient ∣δα(ω, T)∣ is plotted in distinct regimes. The low-frequency(∣ω∣ < T, left) and high-frequency(∣ω∣ > T, right) regimes are separated by a blue shaded region.
