Abstract

In the superdense stage-1 compound of the LiC_x system the spin-lattice relaxation rate T₁^-11 of ⁸Li (T_1/2 = 0.8 s) was measured with the β-NMR method. The T₁^-1 measurements were done in the ampoules of the high-pressure intercalation synthesis and covered the temperature range between 4.2 K and 320 K and external B→ fields between 8.2 mT and 1.7 T for the orientations B→||c→ and B→ ⊥ c→. For B above 100 mT no B→ dependence was found. The linear increase of T₁^-1 with T is ascribed to coupling to conduction electrons and is discussed in terms of a local density of states. No diffusion induced T₁^-1 contribution was observed below 320 K.
