Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction

Abstract

The Dzyaloshinskii-Moriya interaction (DMI) is crucial to the stabilization of skyrmions but the contribution is not well understood. Here, the authors provide a methodology using the single electron spin of a nitrogen-vacancy center to image the fine structure of skyrmions which is attributed to the competition between the DMI and stray fields.
