Abstract
The electronic ground state of CeNiSn has been investigated by means of specific-heat measurements below 2 K in magnetic field up to 5 T using a high-quality single crystal. Unusual temperature and field dependence of specific heat reveals that the density of states of CeNiSn has a peak at inside the pseudogap. We claim that CeNiSn is no longer a Kondo insulator but a metal at the lowest temperature.
