- Abstract: The newly discovered noncentrosymmetric superconductor ThCoC 2 exhibits numerous types of unconventional behavior in the field dependent heat capacity data. Here we present the first measurement of the gap symmetry of ThCoC 2 by muon spin rotation and relaxation ( μ SR ) measurements. The temperature dependence of the magnetic penetration depth measured using the transverse field μ SR experiment reveals the evidence of a nodal pairing symmetry. To understand this finding, we carry out calculations of the superconducting pairing eigenvalue and eigenfunction (pairing symmetry) due to the spin-fluctuation mechanism by directly implementing the ab initio band structures. We find that the system possesses a single Fermi surface with considerable three dimensionality and a strong nesting along the k z direction. Such nesting promotes a superconducting state with a cos k z -like pairing symmetry with a prominent nodal line on the k z = ± π / 2 plane. The result agrees well with the experimental data.
