| Abstract: | The impurity and lattice contributions to the spin-lattice relaxation of Al27 nuclei in nominally pure and lightly chromium-doped corundum (Al2O3) crystals are separated experimentally under the conditions of additional stationary resonance magnetic saturation of a pulsed
NMR signal. The relaxation time T
i
lat
due to the lattice mechanism of the spin-phonon interaction is determined.
