Skyrmion Clusters
An electric‐field‐driven cascading transition of skyrmion clusters in a nanostructured ferromagnetic/ferroelectric multiferroic heterostructure is realized by Zhipeng Hou, Yangfan Hu, and co‐workers, as described in article number 2107908, allowing a continuous multilevel transition of the number of skyrmions in a one‐by‐one manner. Most notably, the transition is nonvolatile and...
Magnetic skyrmions are topological swirling spin configurations that hold promise for building future magnetic memories and logic circuits. Skyrmionic devices typically rely on the electrical manipulation of a single skyrmion, but controllably manipulating a group of skyrmions can lead to more compact and memory‐efficient devices. Here, an electric‐field‐driven cascading transition of skyrmion clusters...
