Evidence for the Fulde–Ferrell–Larkin–Ovchinnikov state in bulk NbS2

Abstract

Superconductivity is often destroyed under magnetic field larger than a critical value called Pauli limit. Here, the authors report superconductivity beyond the Pauli limit in bulk single crystals of NbS2, suggesting the development of a Fulde-Ferrell-Larkin-Ovchinnikov state.
