Light changes a magnet’s polarity
The researchers used a laser pulse (blue) to change the polarity of a ferromagnetic state in a special material consisting of twisted atomic layers (red). (Visualisation: Enrique Sahagún, Scixel / ETH Zurich, University of Basel) Researchers at ETH Zurich and the University of Basel have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light. In a ferroma
