Dynamics of noncollinear antiferromagnetic textures driven by spin current injection
Dynamics of noncollinear antiferromagnetic textures driven by spin current injection
We present a theoretical formalism to address the dynamics of textured, noncollinear antiferromagnets subject to spin current injection. We derive sine-Gordon type equations of motion for the antiferromagnets, which are applicable to technologically important antiferromagnets such as ${\mathrm{Mn}}_{3}\mathrm{Ir}$ and ${\mathrm{Mn}}_{3}\mathrm{Sn}$, and enables an analytical approach to domain wall dynamics in …
