| Abstract: | Nuclear magnetic resonance spin-lattice relaxation rates for 1H in quasicrystalline Ti45Zr38Ni17H x are presented as a function of temperature and hydrogen concentration x. The temperature dependence demonstrates that the relaxation is via interaction with conduction electrons. The relaxation rate is extremely sensitive to hydrogen content, with the rate changing by a factor of as much as two for samples that differ in x |
