Researchers demonstrate room temperature laser control of magnons in thin magnetic materials Visible light pulses tune magnetic frequencies without cryogenic conditions Nanometer scale magnets show ...

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

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 ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

(Nanowerk News) When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the ...

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 ...
