Physical properties of a new barium niobium sulfide, BaNb 2S 5
Abstract
A new barium niobium sulfide, BaNb 2S 5, has been successfully synthesized. The X-ray powder diffraction pattern is indexed on the basis of a hexagonal unit cell with the lattice constants a = 3.32 Å and c = 24.88 Å. BaNb 2S 5 is metallic in electrical resistivity down to 1.9 K and shows paramagnetism in magnetic susceptibility down to 60 K. Thermoelectric power data indicate that BaNb 2S 5 is a n-type metal at temperatures higher than ∼30 K from the standpoint of a single band model.
