16. In ferromagnets which nonuniformities are beyond the linearized spin waves, there is a nonlinear q2 contribution to damping [see J. Foros, A. Brataas, Y. Tserkovnyak, and G. E. W. Bauer, arXiv:0803.2175 (unpublished)] which has a different physical origin, related to the longitudinal spin-current fluctuations.
17. Although both σ and χ are in principle tensors in transverse spin space, they are proportional to δab in axially symmetric systems; hence we use scalar notation.
