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...
