Detecting a Single Skyrmion
In article number 2207770, Haifeng Du, Lingyao Kong, and his co‐workers combine Lorentz‐transmission electronic microcopy with anisotropic magnetoresistance detection on single dipolar skyrmions. This study reveals magnetic field, skyrmion helicity, and skyrmion counts dependence on magnetoresistance and promotes the reading functions of skyrmionic devices.
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...
