Effects of Fermi surface and superconducting gap structure in the field-rotational experiments: A possible explanation of the cusp-like singularity in YNi${}_2$B${}_2$C

Masafumi Udagawa, Youichi Yanase, Masao Ogata

We have studied the field-orientational dependence of zero-energy density of states (FODOS) for a series of systems with different Fermi surface and superconducting gap structures.…
