Edge states and skyrmion dynamics in nanostripes of frustrated magnets

摘要: Magnetic skyrmions are particle-like topological excitations recently discovered in chiral magnets. Their small size, protection and the ease with which they can be manipulated by electric currents generated much interest using for information storage processing. Recently, it was suggested that additional degrees of freedom exist magnetically frustrated materials. Here, we show dynamics antiskyrmions nanostripes magnets is strongly affected complex spin states formed at stripe edges. These create multiple edge channels guide skyrmion motion. Non-trivial topology gives rise to current-induced dynamics, such as emission skyrmion-antiskyrmion pairs. The edge-state controlled an current through exchange between edges a magnetic nanostructure.
