Large amplitude vortex gyration in Permalloy/Bi${}_2$Se${}_3$-like heterostructures

P. N. Skirdkov, K. A. Zvezdin, A. D. Belanovsky +4

We consider the excitation of large amplitude gyrotropic vortex core precession in a Permalloy nanodisk by the torques originating from the in-plane microwave current flowing along…
