Abstract
63 Cu nuclear spin-lattice relaxation rate (1/ T 1 ) in a Kondo lattice compound CeCu 6 has been measured at zero external field down to 60 mK by the PQR technique. 1/ T 1 is almost temperature independent above 6 K, reflecting the Curie-Weiss behavior of the magnetic susceptibility. Below 6 K, 1/ T 1 becomes temperature dependent with decreasing temperature. Then below ∼0.2 K 1/ T 1 follows the T 1 T =const. relation, showing that the Fermi liquid state has set in. The cross-over from the magnetic regime to the non-magnetic Fermi liquid one has been explored in a typical Kondo lattice compound from a microscopical point of view.Keywords
