The spin–lattice relaxation in the metal–hydrogen systems on the basis of transition metals of the IVb subgroup

The spin-lattice relaxation times in the systems Ti–H, Zr–H, and Hf-H were measured by the spin-echo method as functions of temperature and hydrogen concentration. The theoretical values of T1 min. were calculated in the temperature range where ω τc = 1.4. Comparison of the theoretical and experimental values T1 min. allowed to appreciate the translational diffusion contribution and the possible electronic contribution in the spin-lattice relaxation. The parametres of the hydrogen self-diffusion were found. The results are in satisfactory agreement with theoretical concepts developed by Bloembergen et al. [1] and Torrey [2, 3].
