New state of matter holds promise for ultracompact data storage, processing. The observation in a ferroelectric material of “polar vortices” that appear to be the electrical cousins of magnetic skyrmions holds intriguing possibilities for advanced electronic devices. These polar vortices, which were theoretically predicted more than a decade ago, could also “rewrite our basic understanding of ferroelectrics”.
“It has long been thought that rotating topological structures are confined to magnetic systems and aren’t possible in ferroelectric materials, but through the creation of...
