Effective Gilbert damping in the stochastic Landau-Lifshitz-Gilbert equation

Mexx. E. Y. Regout, Bertrand Dupé, Matthieu J. Verstraete

Quasi particle based (e.g. Boltzmann equation) studies of spin wave transport often assume that their scattering rates follow the simple form $\eta =\alpha \omega$, with the Gilbert damping $\alpha$ a…
