Abstract :
Single crystals of BaVS3 were synthesized by a new technique; grown in melted tellurium. The crystals were obtained in the form of large needle with typical dimensions of about 10mm in length and 1mm in width. The electrical resistivity gradually decreased with decreasing temperature from 300K to 130K, which clearly showed a metallic behavior, but steepy increased at 70K. It was firstly found out that a change of the gradient in the temperature dependent resistivity occurred at 250K. This is caused by a structural transformation, demonstrating the crystals grown by our technique with high-quality.
