Abstract

Antimony (Sb) substitution of less than 8% was examined on a single crystal of a layered superconductor NdO_0.7 F_0.3 BiS₂. The superconducting transition temperature of the substituted samples decreased as Sb concentration increased. A lattice constant along the c-axis showed a large decrease compared with that along the a-axis. Since in-plane chemical pressure monotonically decreased as Sb concentration increased, the suppression of the superconductivity is attributed to the decrease in the in-plane chemical pressure.
