Analytic theories for magnetic skyrmions
Magnetic Skyrmions are topologically protected quasi-particles that have proposed uses in future spintronic memory systems. Manipulation of the systems is ideal for these memory devices because of the low energy required to move them through the thin film. Current semi-analytical expressions exist for predicting the size and shape of skyrmions based on material parameters of a thin film but are not easily applied. This work presents fully analytic expressions for the various energy contributions which can be minimized to find a favored size and shape of the skyrmion.
