Description
An external magnetic field causes a significant (more than twofold) increase of γ deduced from high-temperature-range data (i.e., the paramagnetic state) showing no saturation even at 7.5 T, and a slight rise of the electronic specific-heat coefficient for the magnetically ordered state up to ∼125 mJ/mol K2 with saturation at this value in a much lower field (2.5 T). The entropy (ΔS) associated with the ferrimagnetic phase transition is estimated to be 2.9 J/mol K, which is only 0.35R or 50% of the theoretically expected R ln2 value. The heat-capacity and resistivity measurements suggest that CePtGe2 is a moderately heavy-fermion system
