The preliminary results of a study of the ferrimagnetic resonance properties of single crystals of rare earth iron garnet containing samarium, gadolinium, dysprosium, holmium, erbium, and ytterbium are presented. The measurements have been conducted in the temperature region from 77 deg K to 550 deg K at microwave frequencies in the x band. The effective g values and line widths are consistent with the previously reported measurements on polycrystalline samples. In this temperature region the anisotropy energy of the Sm, Gd, Er, and Yb crystals can be represented by the usual cubic form with a negative first order term. The line widths exhibit a large anisotropy which increases with decreasing temperature. (auth)
