Skyrmion, a concept originally proposed in particle physics half a century ago, can now find the most fertile field for its applicability, that is, the magnetic skyrmion realized in helimagnetic materials. The spin swirling vortex-like texture of the magnetic skyrmion can define the particle nature by topology; that is, all the constituent spin moments

Morse theory and the Skyrmion-Skyrmion potential
Physical Review D, 1991We apply the Ljusternik-{hacek S}nirelman theory, a derivative of Morse theory, to the Skyrmion-Skyrmion potential in the two-flavor Skyrme model to look for the existence of new, static, classical solutions in the sector with baryon number two. Concomitantly, we present a systematic method for obtaining an expansion of this potential, in inverse ...

Deformation of magnetic skyrmion due to skyrmion–skyrmion interaction
Chinese Physics BAbstract Understanding skyrmion–skyrmion interactions and their dynamical effects is crucial for skyrmion-based applications. In this article, we investigate the deformation of skyrmions induced by the inter-skyrmion interaction in both static and dynamic scenarios for a two-skyrmion system.

Eliminating Skyrmion Hall Effect in Ferromagnetic Skyrmions
Nano LettersSkyrmion Hall effect (SkHE) remains an obstacle for the application of magnetic skyrmions. While methods have been established to cancel or compensate SkHE in artificial antiferromagnets and ferrimagnets, eliminating intrinsic SkHE in ferromagnets is still a big challenge.

An important application of spin dynamics is the response of a magnetic material subjected to an external stimuli. In the previous chapter we discussed the response of primarily ferromagnets to temperature fluctuations that manifest itself to spin excitations and magnons.

Skyrmions are a class of solitons, which are both topologically stable, meaning that their vacuum manifold has a non-trivial π_3 homotopy group, and energetically stable, meaning that they are local minima of the field energy. The non-linear sigma model is an effective hadronic field theory, based on a triplet of pion fields, which is a low energy ...
