Topological spintronics with antiskyrmions and bimerons

Skyrmions are topologically protected spin textures, which may be used in spintronic devices for information storage and processing. However, skyrmions in ferromagnets have some intrinsic difficulties for their usage in nanodevices, such as the inability to move strictly along electric current due to skyrmion Hall effect. We worked out several routes to solve this problem by using instead of skyrmions novel anisotropic topological objects, such as antiskyrmions and bimerons. Yet as another solution to eliminate the skyrmion Hall effect, topological spin solitons in antiferromagnets are proposed. It will demonstrate how they can be stabilized and manipulated at finite temperatures. Remarkably, we also show how the Magnus force acting on (anti)skyrmions, and thus in turn skyrmion Hall effect, can be efficiently tuned microscopically via modulation of spin-orbit interaction.
