Abstract

The measurement of ultrasonic attenuation α of the highly anisotropic s-wave superconductor YNI₂B₂C was discussed. The measurement was done for all the symmetrically independent elastic modes to explore the location of the zero superconducting gap on the Fermi surface. A pronounced anisotropy of the temperature dependent attenuation in superconducting state was found during the experiment. It was also found that the anisotropy can be interpreted consistently as the presence of zero superconducting gap.
