Magnon lifetime
WebJul 14, 2024 · In principle, this can be achieved by rapid tuning of energy levels between the photon and magnon. However, such tuning has depended on changing the geometric configuration of the device. That typically requires much longer than the magnon lifetime — on the order of 100 nanoseconds (one-hundred billionths of a second). This lack of a … WebNov 14, 2024 · Here, we show that the doping affects the lifetime of magnons and the shape of their dispersion. This results in an increased magnitude of the resonant enhancement of SSE, which becomes...

WebOct 15, 2024 · The elementary spin excitations in strongly magnetic materials are collective spin deviations, or spin waves, whose quanta are called magnons. Interest in the experimental and theoretical investigation of magnons attracted many groups worldwide about 4–6 decades ago and then waned for some time.
WebLifetime of magnon arising from magnon-magnon interaction is studied for the general helical spin system by spin wave approach using diagrammatic techniques. The … WebSep 13, 2024 · The paramagnon lifetime is longer than the charge carrier-magnon interaction time; its spin-spin spatial correlation length is larger than the free-carrier effective Bohr radius and de Broglie wavelength. Thus, to itinerant carriers, paramagnons look like magnons and give a paramagnon-drag thermopower.
WebApr 13, 2024 · In some recent works, the lifetime of the thermal magnons in YIG was estimated using a single parabolic dispersion [ 8 ], which however is valid only for GHz magnons and deviates far from the real spectra for GHz magnons.
