Stable topological textures in a classical 2D Heisenberg model

E. G. Galkina, E. V. Kirichenko, B. A. Ivanov +1

We show that stable localized topological soliton textures (skyrmions) with ${\pi }_2$ topological charge $\nu \ge 1$ exist in a classical 2D Heisenberg model of a ferromagnet with uniaxi…
