Abstract
In order to determine the superconducting gap structure of the borocarbide superconductor YNi2B2C, we have measured the angular variation of the c-axis thermal conductivity κzz in magnetic field rotated within the ab-planes. A clear fourfold symmetry with narrow cusps was observed in the angular variation of κzz. These results provide a strong evidence that the gap function has point nodes which are located along the a- and b-axes of the crystal.
