But powerful magnets are usually large and energy hungry. Chukun Gao at the Swiss Federal Institute of Technology in Zurich ...

Scientists have used light to visualize magnetic domains, and manipulated these regions using an electric field, in a quantum antiferromagnet. This method allows real-time observation of magnetic ...

Light beams of varying intensities (yellow cylinders) help visualize magnetic domains (light and dark areas), separated by domain walls (red lines). When something draws us in like a magnet, we take a ...
