Influence of chemical substitutions on the charge instability of BaVS3

We study the influence of Sr substitutions on the structural counterpart of the MI transition of BaVS3. When Sr content increases, the commensurate CDW modulation of pure BaVS3 is changed into an incommensurate short range modulation that we attribute to a charge ordering of the e(t(2g)) electrons. The same features are observed in S deficient samples. (C) 2007 Elsevier B.V. All rights reserved.
