Photomagnetic effect

The photomagnetic effect refers to the phenomenon where the magnetic properties of a material change when it is exposed to light. This effect is often observed in certain types of materials, particularly those that exhibit a combination of magnetic and optical properties, such as magnetic semiconductors or materials with specific electronic configurations. When a material experiences illumination, the absorption of photons can lead to changes in the electronic states of the material, which in turn can influence its magnetic ordering.
