Abstract :

Magnetic skyrmions are chiral magnetisation windings that can be pictured as minuscule circular magnetic domains bounded by chiral domain walls. Owing to their potential nanometre size and predicted efficient current-driven motion, magnetic skyrmions hold great promise as future information carriers in high-density non-volatile memory and logic applications. Their recent observation at room temperature in material stacks consisting of heavy metal/ferromagnet/non-magnet has lifted an important bottleneck towards the practical realisation of skyrmion-based devices.
