This paper reports an experimental demonstration of efficient excitation of fundamental dark spin wave solitons on a magnonic active ring below self-oscillation threshold by means of a biharmonic technique. This technique is shown to be especially appropriate for implementing multisoliton regimes otherwise unattainable. Theoretical analysis has revealed a very important role played by the phase relations between individual harmonics generated nonlinearly in the process of the formation of multiple solitons. The proposed ad hoc approach making use of the inverse Fourier transform has allowed us to elucidate the mechanisms underlying the formation of investigated nonlinear waveforms from their power spectra.

磁振子有源环中强制双谐波振荡的基波多重暗孤子的激励


本文报道了通过双谐波技术在低于自振荡阈值的磁振子有源环上有效激发基波暗自旋波孤子的实验演示。该技术被证明特别适用于实施原本无法实现的多孤子方案。理论分析揭示了在多个孤子形成过程中非线性产生的单个谐波之间的相位关系起着非常重要的作用。利用逆傅里叶变换的 Ad Hoc 方法使我们能够从其功率谱中阐明所研究的非线性波形形成的潜在机制。
