Abstract

We have successfully synthesized the new BiS2-based superconductor NdOBiS2 by F doping. This compound is composed of superconducting BiS2 layers and blocking NdO layers, which indicates that the BiS2 layer is analogous to the CuO2 layer in cuprates or to the Fe-As layer in Fe-based superconductors. We can obtain NdO 1-xFxBiS2 with bulk superconductivity by a solid-state reaction. Therefore, NdO1xFxBiS2 should be a suitable material for elucidating the mechanism of superconductivity in the BiS2 layer.
