Explanation
A materials with magneto-optical phenomena. When light passes through transparent magnetic materials or is reflected by magnetic materials, various special chemical phenomena can be observed due to the anisotropy of light due to the existence of spontaneous magnetization. These phenomena are collectively called magneto-optical phenomena, such as Faraday effect, Kerr effect, etc. The materials used in this field are mainly magneto-optical material in the form of thin films.
