A team of researchers from the University of Michigan and Rutgers University has discovered a rotational form of spontaneous crystallographic ordering in a ferroic material. In their paper published in the journal Nature Physics, the group describes their work with ferro-rotational orders under different conditions and what they learned about them. Manfred Fiebig with ETH Zurich has published a News & Views piece on the work done by the team in the same issue—he also gives a brief history of ferromagnetism and what has been learned about it over the past 2,000 years.
