要旨:
Results of the susceptibility, specific heat and thermal expansion are reported for the compounds CeM2Ge2 (M: Ag, Au, Ru), which order antiferromagnetically below TN = 5 K (Ag) and 15 K (Au) and ferromagnetically below Tc = 7.5 K (Ru). Distinct maxima in the electronic specific heat coefficient γ(T) at 0.3 K for the Ag- and Au-based compounds hint at a coexistence of coherent electronic quasiparticles of “medium”-heavy mass with magnetic order.
