摘要：

BaVS3 has an hexagonal structure (space group P63/mmc), with chains of V4+ running along the C direction and largely separated from each other. Small single crystals of BaVS3 prepared by flux method in BaCl2 show evidence of 1D antiferromagnetic ordering below 70 K as previously observed on powder samples. The sulphur deficient compound gives ferromagnetic ordering below 16 K with an easy axis of magnetization along the C direction. BaVxTi(1-x)S3 powder samples with 0 <x <1 of the same crystal symmetry as BaVS3 have also been prepared and the effects of changing the population of d electrons along the V-Ti chains, from 0 electron per site, (BaTiS3) to 1 electron per site, (BaVS3) have been studied by X-ray, magnetic and resistivity measurements. A band model is suggested to explain these data. © 1979.
