标题： Chaotic Spin-Wave Solitons in Magnetic Film Feedback Rings

摘要： 在磁性薄膜有源反馈环中首次观察到了混沌自旋波孤子。 在某些环增益水平下，可以观察到环中自生成一个单自旋波孤子脉冲。 当脉冲在环中循环时，其幅度随时间发生混沌变化。 基于增益损耗非线性薛定谔方程的数值模拟再现了观察到的响应。 显示英文摘要

摘要： Chaotic spin-wave solitons in magnetic film active feedback rings were observed for the first time. At some ring gain level, one observes the self-generation of a single spin-wave soliton pulse in the ring. When the pulse circulates in the ring, its amplitude varies chaotically with time. Numerical simulations based on a gain-loss nonlinear Schr\"odinger equation reproduce the observed responses.
