"Unlocking the Magnetic Power: Scientists Harness Light Inside a Magnet"
Researchers have discovered a way to trap light inside a magnetic van der Waals material, a type of two-dimensional metamaterial. By shining light on the material, it interacts with excitons, creating a strong magneto-optic response and making the material 10 times more magnetic. This breakthrough could lead to the development of magnetic lasers and optically controlled magnetic memory.
