Controlled nonlinear magnetic damping in spin-Hall nano-devices

Controlled nonlinear magnetic damping in spin-Hall nano-devices

Nonlinear damping enhancement imposes strict limitations on the operation and efficiency of magnetic nano-devices. Here the authors show that nonlinear damping can be controlled by the ellipticity of magnetization precession, which provides a route for the implementation of efficient active spintron...
