Magneto-optic phenomena refer to the effects that magnetic fields have on the behavior of light in certain materials. When light passes through these materials, its polarization can change due to the influence of an external magnetic field. This interaction is utilized in various applications, such as in optical isolators and magneto-optic storage devices. One of the most well-known magneto-optic effects is the Faraday effect, where the plane of polarization of light rotates when it travels through a material in the presence of a magnetic field. This phenomenon is significant in fields like telecommunications and data storage, where controlling light is essential for efficient information transfer.
