The EPR and spin-lattice relaxation are studied of impurity rare-earth ions in LiLuF/sub 4/ crystals at liquid-helium temperatures. It is detected that paramagnetic relaxation of Er/sup 3 +/ ions is retarded by the effect of the phonon throat. The effect of resonance attenuation of the phonon throat is clarified in two-phonon resonance relaxation processes of Er/sup 3 +/ ions. The Debye temperature of the crystal is determined from an analysis of experimental results.
