- Abstrakt
We report on non-Fermi liquid features observed for CeNi9Ge 4 - a novel stoichiometric compound, which is close to the heavy-fermion quantum critical point. The specific heat measured down to 80 mK reveals an almost logarithmic divergence of the low-temperature contribution yielding an extraordinarily large Sommerfeld value ? exceeding 6 J/mol K2. The application of external magnetic fields recovers a conventional Fermi-liquid state. Œ2003 Elsevier B.V. All rights reserved.
