摘要:

首次在磁性薄膜主动反馈环中观察到了混沌自旋波孤子。在一定的环增益水平下,观察到环中单个自旋波孤子脉冲的自产生。当脉冲在环中循环时,其幅度随时间混沌地变化。基于增益-损耗非线性薛定谔方程的数值模拟再现了所观察到的响应。

英文摘要:

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 Schrödinger equation reproduce the observed responses.
