The wildly increasing use of big data technologies and cloud-based data services means that the global demand for data storage is constantly expanding -- along with the need for ever-faster data processing. At the same time, the currently available technologies will not be able to keep up forever.
How do magnetic waves behave in antiferromagnets and how do they spread? What role do "domain walls" play in the process? And what could this mean for the future of data storage? These questions are the focus of a recent publication in the journal Physical Review Letters from an international research team led by Konstanz physicist Dr Davide Bossini.
