Phase diagram and stability of skyrmion configurations in anti-ferromagnetic materials lacking inversion symmetry
Summary
We investigate the skyrmion configuration in anti-ferromagnetic materials lacking inversion symmetry, specifically its stability compared to other phases in such materials. A model for magnetic structures in anti-ferromagnetic materials is used to calculate the energies of skyrmion states, and homogeneous and spiral states. One finds that the skyrmion configuration can exist as a stable state among homogeneous and spiral states. At the same time, a point-by-point approach lets us construct a primitive phase diagram, which can be used to guide future Monte-Carlo simulations.
