Abstract

We have studied the pressure dependence of the specific heat in a CeNi single crystal using a clamp-type pressure-cell up to 0.8 GPa. The pressure dependence of the electronic specific heat coefficient is found to exhibit a sharp drop at 0.3-0.4 GPa. The present result indicates the instability of a mixed valence state of 4f electrons.
