What is magneto optic?

Magneto-optics is a phenomenon that occurs when polarized light interacts with a magnetic field. This interaction results in a rotation of the plane of polarization of the light. The amount of rotation depends on the strength of the magnetic field and the properties of the material being used.

Magneto-optical materials are materials that can exhibit magneto-optic effects. These materials include iron garnets, rare earth-transition metal alloys, and magnetic multilayer films.

Magneto-optic technology is used in various applications, including data storage, optical sensors, and imaging systems. One of the most common applications of magneto-optic technology is in magneto-optic disks used for data storage. These disks use a thin layer of magneto-optic material that changes its magnetic properties when exposed to a magnetic field. This change in magnetic properties results in a change in the polarization of the light that is used to read and write data on the disk.

Magneto-optic technology is also used in optical sensors and imaging systems. Magneto-optic sensors can be used to detect magnetic fields, while magneto-optic imaging can be used to visualize magnetic structures and magnetic fields.
