Chiral skyrmions of large radius
Stavros Komineas, Christof Melcher, Stephanos Venakides
We study the structure of an axially symmetric magnetic skyrmion in a ferromagnet with the Dzyaloshinskii-Moriya interaction. We examine the regime of large skyrmions and we identi…

The profile of chiral skyrmions of small radius
Stavros Komineas, Christof Melcher, Stephanos Venakides
Chiral skyrmions are stable particle-like solutions of the Landau-Lifshitz equation for ferromagnets with the Dzyaloshinskii-Moriya (DM) interaction, characterized by a topological…

Curvature stabilized skyrmions with angular momentum
Christof Melcher, Zisis N. Sakellaris
We examine skyrmionic field configurations on a spherical ferromagnet with large normal anisotropy. Exploiting variational concepts of angular momentum we find a new family of loca…
