• Ferrimagnetic reasonance experiment in a single crystal and polycrystalline samples has been carried out by a usual microwave technique. It has been found, for the single crystal, that the temperature variations of the g-factor and the line width are similar to those of erbium-iron garnet (ErIG) except for the existence of a broad maximum in line width at about 200°K. These behaviors agree well with Kittel's theory proposed recently. At room temperature, g_<eff> = 1.32, ΔH = 600oe (anisotropy in line width having been hardly observed) and K_1/M_3 = -400oe (which is an order of magnitude larger than that of YIG). For polycrystalline samples, g_<eff> is essentially the same as for the single crystal sample. In the absorption curve, a secondary peak appears, below 200°K, in the lower magnetic field side of the main absorption peak. Electronic state of Eu^<3+> in the garnet crystal is briefly discussed.
