- Abstract
Magnetic skyrmions are localized particle‐like nontrivial swirls that are promising in building high‐performance topological spintronic devices. The read‐out functions in skyrmionic devices require the translation of magnetic skyrmions to electrical signals. Here, combined real‐space magnetic imaging and anisotropic magnetoresistance studies on dipolar skyrmions are reported. A single skyrmion chain and single skyrmion are observed using Lorentz transmission electron microscopy imaging. Meanwhile, the field, helicity, and skyrmion count dependence of anisotropic magnetoresistance of the Fe3Sn2 nanostructures are obtained simultaneously. These results demonstrate that the anisotropic magnetoresistance of skyrmions is independent of the helicity and proportional to the skyrmion count. This study promotes read‐out operations in skyrmion‐based spintronic devices.
