Figure 2

Gilbert damping, obtained from numerical integration of Eq. (8), shows almost no temperature dependence associated with thermal redistribution of conduction electrons. Dashed lines are plotted for Δ = 1 meV for τ = 1 and τ = 10 ns, whereas solid lines stand for Δ = 0.2, 0.3, and 1 meV for τ = 100 ns.
