is a clean paramagnetic Kondo lattice which displays non-Fermi-liquid behavior. We report a detailed investigation of the specific heat, magnetic Grüneisen parameter (), and temperature derivative of the magnetization () on a high-quality single crystal at temperatures down toK and magnetic fields up to 7 T.anddisplay a divergence upon cooling and obeyscaling. Similar behavior has previously been found in several other Yb-based Kondo lattices and related to a zero-field quantum critical point without fine tuning of pressure or composition. However, in the approach ofthe electronic heat capacity coefficient ofsaturates at low, excluding ferromagnetic quantum criticality. This indicates thatscaling is insufficient to prove a zero-field quantum critical point.
