论文摘要
在本文中，我报告了由Yttrium-Iron-Garnet（YIG）制成的磁性薄膜中非线性自旋动力学的数值研究。该膜暴露于面积的小型磁场和强旋流电流。各种各样的发现涵盖了动态制度，托有局部，非传播的孤子，这是一种湍流的混沌制度，该制度将其凝结成具有非类别旋转质地的准静态相。最终，在最大的自旋电流下，建立了一个同质切换状态。
In this article I report about a numerical investigation of nonlinear spin dynamics in a magnetic thin-film, made of Yttrium-Iron-Garnet (YIG). This film is exposed to a small in-plane oriented magnetic field, and strong spin currents. The rich variety of findings encompass dynamic regimes hosting localized, non-propagating solitons, a turbulent chaotic regime, which condenses into a quasi-static phase featuring a non-collinear spin texture. Eventually, at largest spin current, a homogeneously switched state is established.
