In this section, the results of an experimental study of the spectral dependencies of magnetic circular dichroism (MCD) in the wavelength range between 300 nm and 600 nm are reported, conducted with [Bi.sub.2][Dy.sub.1][Fe.sub.4][Ga.sub.1][O.sub.12] iron garnet films of thicknesses 0.6 nm, 1.7 nm, 3.7 nm, 10.3 nm, and 100 nm at room temperature.
That means there are low losses associated with the chirality and then low circular dichroism. The value of the equivalent Pasteur parameter can be calculated from this data, following (3) and (4).
