title: New non-magnetically ordered heavy-fermion system CeTiGe.
abstract: Investigations of the susceptibility, electrical resistivity, specific heat and thermopower of CeTiGe at low temperatures show that this compound is a Kondo lattice system with an enhanced Sommerfeld coefficient γ≈0.3 J K(-2) mol(-1) and where the whole J = 5/2 multiplet is involved in the formation of the ground state. No magnetic order was observed down to 0.4 K. In the temperature range below 10 K we observed Fermi-liquid behavior as indicated by a ρ(T)∼T(2) dependence in the electrical resistivity and a linear specific heat and thermopower. Because of these results we classify CeTiGe as a moderate heavy-fermion system with a non-magnetic ground state.
