Stabilization and helicity control of hybrid magnetic skyrmion
arXiv:2308.08238 · doi:10.1088/1361-6463/ad2009
Abstract
The hybrid skyrmion, a type of magnetic skyrmion with intermediate helicity between Bloch and Néel skyrmion, has gained more attraction. It is tolerant toward the skyrmion Hall effect and a potential candidate for quantum bits. We investigated the stabilization and helicity control of the hybrid skyrmion in a two-dimensional magnetic system using an analytical model and micromagnetic simulation. We look at the interplaying factors of the bulk () and interfacial () Dzyaloshinskii-Moriya (DM) interactions along with the dipolar interaction. We show that the hybrid skyrmion can stabilize through the interplay between interfacial DM and either bulk DM or dipolar interaction. We can also control the helicity of the hybrid skyrmion by tuning the ratio of when there is no dipolar interaction, or simply by adjusting the when the is absent. Our results suggest that hybrid skyrmions can exist within mJ/m for Co-based magnetic systems.
