Abstract

The heat capacity and surface impedance of pristine and irradiated YNi₂B₂C at low temperatures were studied. Strong evidence was obtained that the Doppler shift of the delocalized QP spectrum around the vortex core plays an important role in determining the superconducting properties of YNi₂B₂C.
