Nutation spin waves in ferromagnets

Magnetization dynamics and spin waves in ferromagnets are investigated using the inertial Landau-Lifshitz-Gilbert equation. Taking magnetization into account, dispersion relations describing propagation of nutation an arbitrary direction relative to applied magnetic field derived via Maxwell's equations. It is found that inertia causes hybridization electromagnetic ferromagnets, hybrid emerge, redshift frequencies precession initiated, which transforms precession-nutation waves. These effects depend sharply on wave field. Moreover, propagating parallel circularly polarized, while perpendicular elliptically polarized. The characteristics these also analyzed.
