摘要：

We present the temperature dependence of the magnetic susceptibility chi(T), electrical resistivity rho(T) and low-temperature specific heat C(T) of CeRu4Sb12 . chi(T) shows a broad peak around 100 K characteristic to intermediate-valence compounds but the small Weiss temperature of - 26 K and rho(T) suggest that the compound is classified as a Kondo compound. The ground state is very anomalous and non-Fermi liquid behaviors were observed in C/T and rho(T) at low temperatures. (C) 1999 Elsevier Science B.V. All rights reserved.
