Tetragonal Superstructure of the Antiskyrmion Hosting Heusler Compound MnPtSn.

Skyrmions in non-centrosymmetric magnets are vortex-like spin arrangements, viewed as potential candidates for information storage devices. The crystal structure and noncollinear magnetic structure together with magnetic and spin-orbit interactions define the symmetry of the skyrmion structure. We outline the importance of these parameters in the Heusler compound MnPtSn which hosts antiskyrmions, a vortex-like spin texture related to skyrmions.
