Magnetooptical materials

Compared to photographic films, BR is handicapped due to its very low light sensitivity. Also, as a possible material for disk-shaped digital optical information storage, BR does not offer an advantage over estabUshed magnetooptical materials ia spite of its higher line resolutioa, because ia both cases... 

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.

In addition to garnets (see Section 5.4.5), great efforts have been made to prepare new magnetooptical materials involving other R-M systems. 

Once the shortcomings of the low transition temperatures have been solved (presumably by strong, intermolecular interactions in three-dimensional materials), molecular magnets can be expected to contribute to many applications, most likely as magnetooptic materials, where a high flux density is not the basic property. Exciting developments can be foreseen in the near future in this new area.
