Popis:	Nuclear magnetic resonance measurements of 2D spin lattice relaxation rates in C15-ZrCr2Dx (x = 0.29, 0.48 and 3.8) and C14-ZrCr2D4.0 have been performed over the temperature range 110–450 K. The experimental results are analysed to obtain the electronic (Korringa) contributions to the relaxation rates and the parameters of deuterium diffusion. For C15-ZrCr2Dx the deuterium mobility is found to decrease with increasing x. Comparison of the data for ZrCr2Dx and ZrCr2Hx shows that in compounds with nearly the same x the hopping rate of D atoms is lower than that of H atoms.
