Abstract
The transport properties (resistivity ρ, thermopower S, thermal conductivity k) of CeCu2Si2 with unstable 4f shell and of LaCu2Si2 as reference compound were measured between 1.5 K and 300 K. For CeCu2Si2, ρ becomes as large as 220 µΩcm (at 200 K) indicating an electronic mean free path of the order of the Ce-Ce spacing. Correspondingly, below 100 K we infer k ≈ kp (phonon conductivity). The low temperature results of S suggest heavy Fermi liquid behavior with characteristic temperature T* = (30 ± 10) K. Above 20 K, a distinct temperature dependence of both ρ and S originates in the crystal field splitting of the j = 5/2 state of Ce3+ with unstable 4f shell.
