The analytically derived dynamic response upon microwave excitation shows two peaks: ferromagnetic and nutation resonances. The exact analytical expressions of frequency and linewidth of the magnetic nutation resonance are deduced from the frequency dependent susceptibility determined by the inertial Landau-Lifshitz-Gilbert equation. The study shows that the dependence of nutation linewidth on the Gilbert precession damping has a minimum, which becomes more expressive with increase of the applied magnetic field.", "revisions": [ { "version": "v1", "updated": "2020-08-27T16:21:06.000Z" } ], "analyses": { "keywords": [ "ferromagnet", "inertial landau-lifshitz-gilbert equation", "frequency dependent susceptibility", "magnetic nutation resonance", "applied magnetic field" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
