XAFS-spectroscopy of EuCu2Si2

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
We report the results of the intermediate valence compound EuCu2Si2 local electron and crystalline structure studies by means of L3-Eu XANES and K-Cu EXAFS spectroscopy. Temperature dependence of the europium valence has been defined. In EXAFS studies, we have analyzed Cu atoms local environment and have revealed bond length and rigidity parameters of ...

Molecular Dynamics Simulations and XAFS (MD-XAFS)

2016
MD-XAFS (Molecular Dynamics X-ray Adsorption Fine Structure) makes the connection between simulation techniques that generate an ensemble of molecular configurations and the direct signal observed from X-ray measurement. Due to the fact that the signal is most sensitive to the structure nearest to a photoelectron source, an understanding of XAFS signal

XAFS of ZnSe

Physica B: Condensed Matter, 1995
Abstract We present an X-ray absorption study of zinc selenide at the Zn and Se K-edges. The analysis of the X-ray absorption fine structure (XAFS) was done in the framework of the multiple-scattering theory. The total XAFS signals have been obtained; they are in good agreement with the experimental data.

XAFS in dilute magnetic semiconductors

Dalton Transactions, 2013
X-Ray absorption fine structure (XAFS) spectroscopy has experienced a rapid development in the last four decades and has proved to be a powerful structure characterization technique in the study of local environments in condensed matter. In this article, we first introduce the XAFS basic principles including theory, data analysis and experiment in some

Transferability in XAFS

Physica B: Condensed Matter, 1989
Abstract The transferability concept is central to all practical applications of XAFS for structure determination, both experimental and theoretical. In this paper the question of transferability in EXAFS is re-examines. Physical arguments ndicate that transferability is much less accurate for multiple scattering than for single scattering. Therefore
