Magneto-optics is a scientific field that combines the study of magnetism and optics to understand the interaction between light and magnetic fields in various materials. This research area focuses on how light, specifically polarized light, can be influenced by the presence of magnetic fields and how magnetic properties can in turn be modified by the interaction with light. Magneto-optic phenomena have applications in a wide range of technologies, including data storage, imaging, and sensing. Researchers in this field aim to explore and exploit the unique properties of magneto-optic materials to develop new technologies and devices.
