A skyrmion-based spin-torque nano-oscillator


Reference: F. Garcia-Sanchez et al., New J. Phys. 18, 075011 (2016).

We show how inhomogeneous spin polarizers in the form of vortices can result in self-sustained gyration of skyrmions in magnetic nanopillars. We suggest that such dynamics could be useful for skyrmion-based spin-torque nano-oscillators. This work has just appeared in the New Journal of Physics.
