“…This behavior can be explained by the effects of the nonlinear damping and negative nonlinear frequency shift, as analyzed in detail in Refs. [26][27][28]. We note that the anomalous positive nonlinear frequency shift [21] was not observed in the studied samples due to the low efficiency of the edge mode excitation.…”

“…The reason for this asymmetry might be due to the formation of a foldover effect, 37,38 due to nonlinear damping or a nonlinear frequency shift. 39,40 The results of the damping parameter α eff obtained by microwave power dependent spin-pumping measurements are depicted in Fig. 7(b).…”

The dependence of the spin-pumping effect on the yttrium iron garnet (Y 3 Fe 5 O 12 , YIG) thickness detected by the inverse spin Hall effect (ISHE) has been investigated quantitatively. Due to the spin-pumping effect driven by the magnetization precession in the ferrimagnetic insulator Y 3 Fe 5 O 12 film a spin-polarized electron current is injected into the Pt layer. This spin current is transformed into electrical charge current by means of the ISHE. An increase of the ISHE voltage with increasing film thickness is observed and compared to the theoretically expected behavior. The effective damping parameter of the YIG/Pt samples is found to be enhanced with decreasing Y 3 Fe 5 O 12 film thickness. The investigated samples exhibit a spin mixing conductance of g ↑↓ eff = (3.87 ± 0.21) × 10 18 m −2 and a spin Hall angle between θ ISHE = 0.013 ± 0.001 and 0.045 ± 0.004 depending on the used spin-diffusion length. Furthermore, the influence of nonlinear effects on the generated voltage and on the Gilbert damping parameter at high excitation powers is revealed. It is shown that for small YIG film thicknesses a broadening of the linewidth due to nonlinear effects at high excitation powers is suppressed because of a lack of nonlinear multimagnon scattering channels. We have found that the variation of the spin-pumping efficiency for thick YIG samples exhibiting pronounced nonlinear effects is much smaller than the nonlinear enhancement of the damping.

“…[1][2][3] Recently there has been a renewal of this interest because it has become possible to generate large amplitude precessional motion in metals through a variety of techniques. [4][5][6][7][8][9][10][11] There have been a number of experiments 8,12,13 which have shown an interesting nonlinear mixing of two signals in magnetic materials. These experiments were done in ultra-small geometries where the microwave magnetic field could be varied over several orders of magnitude, from less than one Oe up to several hundred Oe.…”

Recent experiments have shown that two electromagnetic waves can be mixed together by a nonlinear process in magnetic materials and can produce a wide variety of output waves, each with a different frequency. A perturbation expansion of the Landau-Lifschitz-Gilbert equation is presented which provides qualitative and quantitative understanding of this process. The results of this expansion are compared to both experiment and direct numerical solutions.2
