Abstract

Novel BiS₂-based superconductors LaO_1-xF _xBiS₂ prepared by a high-pressure synthesis technique were systematically studied. It was found that the high-pressure annealing strongly shrank the lattice as compared to the LaO_1-xF_xBiS ₂ samples prepared by conventional solid-state reaction at ambient pressure. Bulk superconductivity was observed within a wide F concentration range of x = 0.2-0.7. On the basis of those results, we have established a phase diagram of LaO_1-xF_xBiS₂.
