| 抄録 | We report the Pb-207 nuclear magnetic resonance (NMR) measurements on polycrystalline sample of PbTaSe2 with noncentrosymmetric crystal structure and topological electronic band. The nuclear spin-lattice relaxation rate 1 / T-1) shows a suppressed coherence peak below the superconducting transition temperature T-c = 4.05 K and decreases as an exponential function of temperature. The penetration depth derived from the NMR spectrum is almost temperature independent below T = 0.7 T-c. The Knight shift K decreases below T-c. These results suggest spin-singlet superconductivity with a fully opened gap 2 Delta = 3.5 k(B)T(c) in PbTaSe2.
