Abstract
Magnetic skyrmions (Sks) are vortex-like spin textures with physical properties protected by its topological non-trivial nature. Sks are mostly reported in non-centrosymmetric crystal structures where the antisymmetric Dzyaloshinskii-Moriya interaction plays a key role to stabilize the Sks. However, a non-trivial topological spin structure has been recently observed in a SrFeO_3 crystal …
