Microscopic Investigation of the Superconducting State in CuCo${}_2$S${}_4$: Evidence for an Intermediate-Coupling Fully Gapped Superconductor

K. Panda, A. Bhattacharyya, Liang-Wen Ji +4

The thiospinel compound CuCo${}_2$S${}_4$ provides an attractive platform for exploring superconductivity in transition-metal chalcogenide spinels. Here, we report the first microscopi…
