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