Controlling the helicity of magnetic skyrmions by electrical field in frustrated magnets
The skyrmions generated by frustration in centrosymmetric structures host extra internal degrees of freedom—vorticity and helicity, resulting in distinctive properties and potential functionality, which are not shared by the skyrmions stemming from the Dzyaloshinskii–Moriya interaction in noncentros...

| description | The skyrmions generated by frustration in centrosymmetric structures host extra internal degrees of freedom—vorticity and helicity, resulting in distinctive properties and potential functionality, which are not shared by the skyrmions stemming from the Dzyaloshinskii–Moriya interaction in noncentrosymmetric structures. The present work indicates that the magnetism-driven electric polarization carried by skyrmions provides a direct handle for tuning helicity. Especially for the in-plane magnetized skyrmions, the helicity can be continuously rotated and exactly picked by applying an external electric field for both skyrmions and antiskyrmions . The in-plane uniaxial anisotropy is beneficial to this manipulation. |
