摘要：

The resistivity rho, magnetic susceptibility chi, and specific heat C were measured for a single crystal of the valence-fluctuating hexagonal system CeRhSn. Strong anisotropy in both the resistivity (rho(a) > rho(c)) and magnetic susceptibility (chi(c) > chi(a)) was found. A hump appears in rho(c)(T) below 7 K, where both C/T and chi exhibit strong upturns. Power-law behaviors chi(c) proportional to T-1.1 and chi(a) proportional to T-0.35 were found below 4 and 16 K, respectively, down to 0.4 K. These results suggest the presence of unquenched moments in the quasi-Kagome lattice. (C) 2003 Elsevier Science B.V. All rights reserved.
