Pulsed NMR measurements of the proton spin-lattice relaxation time, T<sub>1</sub>, in yttrium dihydride containing controlled amounts of gadolinium are reported over the temperature range 140-1250K. Addition of gadolinium produces a temperature-dependent relaxation contribution which is proportional to gadolinium concentration and gives rise to a subsidiary minimum on the low-temperature side of the main minimum due to proton-proton dipolar interactions. The results are interpreted in terms of a magnetic dipolar interaction between the Gd<sup>3+</sup> paramagnetic ions and the protons. The possibility that some of the diffusion data deduced from previous NMR measurements has been affected by the unsuspected presence of paramagnetic impurities is discussed. |
