Popis: We report on unusual non-Fermi liquid features of the ternary compound CeNi 9 Ge 4 which exhibits the largest ever recorded value of the electronic specific heat C / T ≃ 5.5 J / mol K 2 at T = 0.08 K in a purely paramagnetic system. The latter is confirmed by μ SR measurements down to 30 mK revealing a rather slow simple exponential muon spin depolarisation in zero-field and thus a spatially homogeneous paramagnetic state. The ground state properties and crystal field (CF) splitting of CeNi 9 Ge 4 have been studied by specific heat, magnetic susceptibility as well as muon spin relaxation ( μ SR) and inelastic neutron spectroscopy (INS).
