The Faraday effect (FR) is investigated experimentally in GdIG (Gd/sub 3/Fe/sub 5/O/sub 12/) single crystals; the magnetic field up to 20 kOe was applied along the (111) direction at a wavelength of 1.15 micron. The 4.2-580 K temperature range covers all the magnetic ordering domain. The Faraday rotation reciprocal susceptibility differs strongly from that observed in other heavy rare earth garnets. In the spontaneous state the results are analyzed using the model where the Fe/sup 3+/ total contribution to FR is the same as that of YIG. At very low temperatures the Gd/sup 3+/ contribution originates from magnetic dipole contribution only; in the 25-425 K temperature range the electric dipole coefficient Ce/sup s/ presents a linear temperature dependence. At the Neel point the GdIg Faraday rotation is going to zero.
