Abstract

Gap function with point nodes in borocarbide superconductor YNi₂B₂C was analyzed. The angular variation of c-axis thermal conductivity in magnetic field rotated with the ab plane showed a peculiar fourfold oscillation with narrow cusps. The results provided the evidence that the gap function had point nodes located along the a and b axes.
