Nuclear magnetic resonance measurements were made of 2D spin lattice relaxation rates in C15 Cr2ZrDx, where x was equal to 0.29, 0.48 or 3.8, and in C14 Cr2ZrD4 at temperatures ranging from 110 to 450K. The experimental results were analyzed in order to obtain the electronic (Korringa) contributions to the relaxation rates and parameters for D diffusion. In the case of C15 Cr2ZrDx, the D mobility was found to decrease with increasing x-value. A comparison of data for Cr2ZrDx and Cr2ZrHx showed that, in samples with almost the same x-value, the hopping rate of D atoms was lower than that of H atoms.
