Magnets tuned with lasers at room temperature could lead to faster hard drives and a new generation of computer chips.

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

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 ...

The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time ...

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 ...
