Dans cet article, nous presentons comment utiliser les oscillations du coefficient d’absorption X (EXAFS) pour determiner la structure et l’ordre local autour d’une espece chimique precise dans un materiau. Une description theorique du phenomene est donnee.

Analytical Chemistry, 1988
The past several years have witnessed the emergence of Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy from an esoteric technique to a widely available structural spectroscopic tool. Several in-depth review articles and books are available on the subject, but some aspects of theory or data reduction may be beyond the scope or need of the ...

Le Journal de Physique IV, 1997
The occurrence of a magnetic contribution in the EXAFS regime is a complex problem but interesting phenomenon since it is expected to contain unique information on the magnetic short-range order. Experimental studies of the small effects with sufficient high accuracy are required to provide the possibility of a reliable data analysis and interpretation.

Journal of Physics C: Solid State Physics, 1980
Polarised X-rays of the Deutsches Elektronen-Synchrotron have been used to measure the anisotropic absorption of a GeS single crystal at the Ge K-edge. The orientation-dependent radial structure functions which have been calculated from the extended X-ray absorption fine structure are used to evaluate the three-dimensional arrangement of the atoms in ...

EXAFS Studies of Metallothionein
1987Extended x-ray absorption fine structure (EXAFS) has been used to investigate the metal environment in a number of metallothioneins (MT). In all cases, the primary coordination sphere consists of sulphur atoms. In some cases, evidence for cluster formation is obtained.

EXAFS and LocalThermal Expansion
Physica Scripta, 2005The sensitivity of X-ray absorption spectroscopy (XAS)to the local structure around a selected atomic species (symmetry,distances and angles)is commonly exploited to quantitatively describe systems where all the configurations around the absorbing atoms may be approximated by the mean on. However,in many cases of disordered systems a simple description

Abstract The extended X-ray absorption fine structure (EXAFS) technique is now used extensively and effectively in the study of the structure of metal catalysts. This paper is a review of the different types of EXAFS experiments, and of the kind of results they give, and it also speculates on the future of the technique in solid-state physics.
