Abstract

We studied the nuclear magnetic resonance (NMR) spin-lattice relaxation time T1 for hydrogen in amorphous metal hydrides of the form (Ni0.5Zr0.5)1-xPxHy as a function of both hydrogen and phosphorus concentration. We found that the hydrogen diffusion contribution dominates T1 over most of the temperature range from 500 K down to 150 K. The diffusion activation energy is of the order of 0.39 eV, but has a wide distribution and, in particular, low energy contributions are present which are appreciable down to the lowest temperatures studied. The Korringa relaxation time T1e controls T1 at the lowest temperatures and highest frequencies used. The system shows single-phase behavior above room temperature but two-phase behavior at 150 K.
