摘要：
We have investigated the crystal structure and superconducting properties of the new layered superconductor NdO1-xFxBiS2. Bulk superconductivity with a T-c above 4.5 K was observed. It was found that the T-c depended on both F concentration and crystal structure. Uniaxial compression along the c axis upon F substitution seemed to be linked with the appearance of bulk superconductivity. Furthermore, we considered that a higher T-c can be achieved when the c/a parameter was optimized in the NdO1-xFxBiS2 system.
