Abstract

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 (Formula presented.) for value for (Formula presented.) and (Formula presented.) is estimated to be approximately 2.17 and 1.72 T respectively by using Werthamer-Helfand-Hohenberg model.
