Local magnetic measurements of few-layer superconducting MoS₂

Under ionic liquid gating, the transition metal dichalcogenide MoS₂ exhibits a superconducting dome with a maximum critical temperature of nearly 10 K in few-layer devices gated with an ionic liquid. Here, we report local magnetic measurements combined with electrical transport of this superconducting state as a function of temperature and over a limited range of carrier density. Using a scanning superconducting quantum interference device with an integrated field coil, we measure local diamagnetism at finite frequency. We report progress in extracting quantitative values of the Pearl length and superfluid density from these measurements.
