Lu, T. Mo, K. Gan, J. Chou, M. Lee] A Ce-based intermetallic compound Ce2CuGe6 and its La analogue La2CuGe6 were synthesized and examined by X-ray powder diffraction, electrical resistivity, magnetic susceptibility, X-ray absorption spectrum and specific-heat measurements. The results reveal that Ce2CuGe6 is an antiferromagnetic Kondo-lattice compound with T N ∼15K. The effective moment deduced from paramagnetic region is 2.58μ B per cerium ion, which is close to localized Ce3+ free ion in 2F5/2 state. X-ray absorption measurement also precluded the existence of an intermediate valence state. The magnetic entropy calculated from heat capacity specific-heat measurement suggested a doublet ground state. In addition, we also observed a spin-glass-like behavior in this material. The spin-glass-like behavior might be due to the complex interplay between magnetic interactions.
