Abstract: We have recently shown that CeRhSn exhibits non-Fermi liquid temperaturę dependences in its low-temperature physical properties. Here we suggest that the non-Fermi liquid behavior observed in CeRhSn may be due to the existence of a Griffiths phase in the vicinity of a quantum critical point, based on electrical resistivity, magnetic susceptibility, and specific heat measurements. For CeRhSn, the low-temperature scaling of bulk properties (C/T oc y oc T _1+A, where A < 1) is masked by an anomaly at about 6 K, which is of magnetic origin.
