Abstract
Nuclear magnetic resonance measurements of D-2 spin lattice relaxation rates in C15-ZrCr2Dx (x=0.29, 0.48 and 3.8) and C14-ZrCr2D4.0 have be en performed over the temperature range 110-450 K. The experimental re sults are analysed to obtain the electronic (Koninga) contributions to the relaxation rates and the parameters of deuterium diffusion. For C 15-ZrCr2Dx the deuterium mobility is found to decrease with increasing x. Comparison of the data for ZrCr2Dx and ZrCr2Hx shows that in compo unds with nearly the same x the hopping rate of D atoms is lower than that of H atoms.
