From Chaotic Spin Dynamics to Non-collinear Spin Textures in YIG Nano-films by Spin Current Injection (2009.10628v1)
Published 22 Sep 2020 in cond-mat.mes-hall
Abstract: 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.
