That branch of physics which deals with the influence of a magnetic field on optical phenomena. Considering the fact that light is electromagnetic radiation, an interaction between light and a magnetic field would seem quite plausible. It is, however, not the direct interaction of the magnetic field and light that produces the known magnetooptic effects, but the influence of the magnetic field upon matter which is in the process of emitting or absorbing light.

No signs of magnetooptic activity were detected in any of the amorphous film samples.
Experimental results have shown that, at temperatures below 160 K, for a film of 1.7 nm thickness, the observed MCD spectrum is mainly due to the presence of [Bi.sub.1][Dy.sub.2][Fe.sub.2.5][Ga.sub.2.5][O.sub.12] nanocrystallites, whereas over the temperature range between 100 K and 8 K, the magnetooptic activity typical of [Bi.sub.1][Dy.sub.2][Fe.sub.2.5][Ga.sub.2.5][O.sub.12] nanocrystallites is dominant.
