ABSTRACT We have successfully synthesized a new BiS2-based superconductor NdOBiS2 with
F-doping. This compound is composed of superconducting BiS2 layers and blocking
NdO layers, which indicates that the BiS2 layer is the one of the common
superconducting layers like the CuO2 layer of cuprates or Fe-As layer of
Fe-based superconductors. We can obtain NdO1-xFxBiS2 with bulk
superconductivity by a solid-state reaction under ambient pressure. Therefore,
NdO1-xFxBiS2 should be the suitable material to elucidate the mechanism of
superconductivity in the BiS2-layer.
