Abstract:
XAFS was first used to study the changes in the local structure and oxidation state of metal ions in CuCr1−xVxS2 (0⩽x<0.25). XANES showed identical monovalent state of Cu1+and Cr3+ ions in this family. EXAFS revealed local structure distortions of Cr and Cu as compared to mother CuCrS2 provided the V content was minor for Cr and more pronounced for Cu. Analysis of the XAFS data showed that the V ions are partly inserted into unfilled sites of the Cr sublattice, but they are mainly located in non-regular sites, saving slightly the distorted octahedral sulfur nearest surrounding. The vacancies in CrS2 slabs, the V distribution and the lattice reduction are considered as factors that can modify the magnetic state of the samples.
