采用熔融金属助熔剂法合成了单晶体CeRu_4Sb_（12）。CeRu_4 Sb_（12）的比热和磁化率可以用对数发散或温度幂律来描述，表明低温下的非费米液体行为。电阻率与样品有关，某些样品在低于类似于5 K的T下表现出非费米液体行为，其中ρ α T-n，n类似于1.4，施加高达H = 80 kOe的磁场不会显着改变非费米液体基态。
We synthesized the filled skutterudite CeRu4Sb12 in single-crystal form using a molten-metal-flux technique with Sb flux. The specific heat and magnetic susceptibility of CeRu4Sb12 are well described by a logarithmic divergence or a power law in temperature indicating non-Fermi-liquid behaviour at low temperatures, The electrical resistivity is sample dependent with some specimens exhibiting non-Fermi-liquid behaviour below T similar to 5 K in which rho alpha T-n with n similar to 1.4, The application of magnetic fields up to H = 80 kOe does not significantly change the non-Fermi-liquid ground state.
