Orenstein We study the magnetic excitations of itinerant helimagnets by applying time-resolved optical spectroscopy to Fe 0.8 Co 0.2 Si. Optically excited oscillations of the magnetization in the helical state are found to disperse to lower frequency as the applied magnetic field is increased; the fingerprint of ... [Phys. Rev.
