Gadolinium-iron garnet

Modulated transducers are used in optical information processing. Faster, and smarter devices are required to control displays, printers and communication equipment. Thin garnet films, with individual pixels, that can be addressed independently and be switched from transparent to opaque can be used in this technology. Light switching arrays (LISA) are composed of bismuth substituted gadolinium iron garnets (GIG).

Reaction Kinetics of Wet Chemically Prepared Gadolinium-Iron Garnet... 

Films of gadolinium-iron garnet, Gd3Fe50j2, have been prepared by Wade et al. ( ) using a wet-chemical method. The technique involves applying an alcoholic solution of gadolinium-iron nitrate to a substrate as a film which is then dried to a nearly amorphous state and fired for conversion to polycrystalline Gd3Fe50j2.
