We report on the temperature dependence of the in-plane magnetic penetration depth (λab) and first penetration field [Hf∝1/λab2(T) for H∥c] in 2H-NbS2 single crystals. An exponential temperature dependence is clearly observed in λab(T) at low temperature, marking the presence of a fully open superconducting gap. This compound is the only...

We performed specific heat measurements of the superconducting single crystal of 2H-NbS2 in the temperature range down to 0.6 K and magnetic fields up to 14 T. The temperature and magnetic field dependence of the electronic specific heat consistently indicate existence of two superconducting energy gaps in the system. The superconducting...
