Magnets are chaotic—and fast—at the very smallest scale

Using a new type of camera that makes extremely fast snapshots with an extremely high resolution, it is now possible to observe the behaviour of magnetic materials at the nanoscale. This behaviour is more chaotic than previously thought, as reported in Nature Materials on 17 March. The observed behaviour changes our understanding of data storage, says Theo Rasing, one of the authors of the article.
