説明

<jats:title>Abstract</jats:title><jats:p>Helicity indicates the in‐plane magnetic‐moment swirling direction of a skyrmionic configuration. The ability to reverse the helicity of a skyrmionic bubble via purely electrical means has been predicted in frustrated magnetic systems; however, it has been challenging to observe this experimentally. The current‐driven helicity reversal of the skyrmionic bubble in a nanostructured frustrated Fe<jats:sub>3</jats:sub>Sn<jats:sub>2</jats:sub> magnet is experimentally demonstrated. The critical current density required to trigger the helicity reversal is 10<jats:sup>9</jats:sup>–10<jats:sup>10</jats:sup> A m<jats:sup>−2</jats:sup>, with a corresponding pulse‐width varying from 1 µs to 100 ns. Computational simulations reveal that both the pinning effect and dipole–dipole interaction play a crucial role in the helicity reversal process.</jats:p>
