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 reversible. These results open up a new direction for constructing low-power-consuming, nonvolatile, and multibit skyrmionic devices.
