Abstract
We synthesized the filled skutterudite CeRu4Sb12 in single-crystal form usi ng a molten-metal-flux technique with Sb flux. The specific heat and magnet ic susceptibility of CeRu4Sb12 are well described by a logarithmic divergen ce or a power law in temperature indicating non-Fermi-liquid behaviour at l ow temperatures, The electrical resistivity is sample dependent with some s pecimens exhibiting non-Fermi-liquid behaviour below T similar to 5 K in wh ich 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.
