Magnetostatic interaction between two bubble skyrmions
(IOP, 2020)
A detailed analytic and numerical analysis of the interaction between two bubble skyrmions has been carried out. The results from the micromagnetic calculations show that when the skyrmions are in the same plane, the ...
Skyrmion dynamics and topological sorting on periodic obstacle arrays
(2020-05-01)
We examine skyrmions under a dc drive interacting with a square array of obstacles for varied obstacle size and damping. When the drive is applied in a fixed direction, we find that the skyrmions are initially guided in ...
Guided skyrmion motion along pinning array interfaces
(2021-06-15)
We examine ac driven skyrmions interacting with the interface between two different obstacle array structures. We consider drive amplitudes at which skyrmions in a bulk obstacle lattice undergo only localized motion and ...

Distinct magnetic field dependence of Neel skyrmion sizes in ultrathin nanodots
(2018)
We investigate the dependence of the Neel skyrmion size and stability on perpendicular magnetic field in ultrathin circular magnetic dots with out-of-plane anisotropy and interfacial Dzyaloshinskii-Moriya exchange interaction. ...
Skyrmion dynamics and transverse mobility: skyrmion Hall angle reversal on 2D periodic substrates with dc and biharmonic ac drives
(2020-06-01)
Abstract: We numerically examine the dynamics of a skyrmion interacting with a two-dimensional periodic substrate under dc and biharmonic ac drives. We show that the Magnus force of the skyrmion produces circular orbits ...
