Tuning Dzyaloshinskii–Moriya interaction via an electric field at the Co/h-BN interface†
The Dzyaloshinsky–Moriya interaction (DMI) at the Co/h-BN interface can emerge and be enhanced by applying a downward electric field. The height of the Co atom relative to the h-BN layer with the electric field determines the variation of DMI. One half reduction of J1 is beneficial to generate skyrmions. Tuning the DMI by an electric field sheds new light for research on skyrmions.
