Abstract
EXAFS measurements have been carried out on the FeXZrS2 series at the Fe K-edge (x = 0.33) and at the Zr K-edge (x = 0.10, 0.25, and 0.33). The Zr-S distances are found to slightly increase with x. The correspo nding Debye-Waller factor increases too, as a result of local distorti ons which are discussed in relation with disorder effects. The iron su rrounding is a regular sulfur tetrahedron.
