摘要: Nuclear magnetic resonance measurements of the proton spin-lattice relaxation rate in C15-type HfMo2H0.4 have been performed over temperature range 20-420 K and frequency 13-90 MHz. The dependence is found to exhibit two peaks. This consistent with a coexistence types H hopping different scales. experimental results are analysed evaluate parameters hydrogen motion electronic (Korringa) contribution rate. Our support idea that ratio characteristic frequencies C15 compounds AB2 related metallic radii elements A B.
