Magnetooptical effects

Magnetooptic Materials. The appHcation of magnetooptic effects to optical memory systems, such as for laser beam writing and magnetooptic read, has been the subject of much research. Magnetooptic storage media offer the potential of storing over 120 Mbit/cm of information without contact of the read/write head which would thus be very competitive to floppy disks and tape.

Often the electronic spin mainly plays the indirect role through the Pauli principle, but in some cases it is directly the source of physical processes. Magnetism is an obvious example, and the combination of spin- and orbital moments determines the magnetic properties of materials. The theory must therefore be able to treat spin-polarization and SO-coupling simultaneously. This is therefore the third subject dealt with here. Magnetoelastic and magnetooptic effects are related to this and are discussed in Section 5. 

Electrooptic and magnetooptic effects involve changes in the refractive index of the medium caused by external electric or magnetic fields resulting in changes in the phase of the optical wave or in its state of polarization.
