Skyrmions in ferromagnets have intrinsic difficulties for use in spintronic applications. Dr Tretiakov discusses how to work around this problem.
Magnetic skyrmions are topological solitons, which are ideal candidates for memory bits in future spintronic devices. However, skyrmions in ferromagnets have some intrinsic difficulties to use them for spintronic applications, such as inability to move strictly along electric current. Dr Tretiakov will discuss how to work around this problem by using instead of skyrmions different topological solitons such as antiskyrmions and bimerons as well as different materials such as antiferromagnets.
