Short film of a magnetic nano-vortex

For the first time, researchers at the Paul Scherrer Institute PSI have recorded a '3D film' of magnetic processes on the nanometer scale. This reveals a variety of dynamics inside the material, including the motion of swirling boundaries between different magnetic domains. The insights were gained with a method newly developed at the Swiss Light Source SLS. It could help to make magnetic data storage devices more compact and efficient. The researchers are publishing the results of their investigations today in the journal Nature Nanotechnology.
