We report on superconducting properties of high-quality single crystals of F-substituted NdOBiS2 using low-temperature magnetization and transport measurements. Using the mixture of CsCl and KCl as the flux, we have synthesized our single crystals. This compound exhibits bulk superconductivity with a transition temperature of about T c∼4.6 K. The critical current density J c as a function of temperature has been derived and decreases with the increasing temperature. We construct the phase diagram H c2(T). The zero-temperature value for \(H_{\mathrm {c2}}^{B\parallel c}\) for value for \(T_{c}^{90~\%}\) and \(T_{c}^{0~\%}\) is estimated to be approximately 2.17 and 1.72 T respectively by using Werthamer-Helfand-Hohenberg model.
