Separation of the impurity and lattice components of the spin-lattice relaxation of Al27 nuclei in corundum crystals under magnetic saturation conditions

Impurity Nuclear Spin–Lattice Relaxation Suppression and Charge Exchange of Chromium Ions in a γ-Irradiated Ruby Crystal

“…Thus, the relaxation time at strong saturation should be treated as T 1 lat . It follows from the measurements performed that T 1 lat ϭ 260 Ϯ 20 s. This time agrees well with the spin-lattice relaxation time corresponding to the lattice contribution which has been found in (19,25) for two different nominally pure Al 2 O 3 crystals (270 and 260 s). The substitution of the values of T 1 ⌺ and T 1 lat into Eq.…”
