Understanding atomic x-ray absorption fine structure in x-ray absorption spectra [PDF]

Journal of Physics: Condensed Matter, 1998
The origin and important parameters determining the intensity of atomic x-ray absorption fine structure (AXAFS) are described both in chemical and physical terms. A full mathematical derivation is presented and new criteria are given for removal of the background to extract the total (EXAFS and AXAFS) from the experimental absorption cross-section. The

Anomalous Behavior in the Atomic Structure of Nb₃Sn under High Pressure

Crystals, 2021
In the present study, the local atomic structure of a Nb3Sn superconductor sample has been probed by X-ray absorption fine structure (XAFS) as a function of hydrostatic pressure (from ambient up to 26 GPa) using a diamond anvil cell set-up.

High-resolution x-ray spectrometer for x-ray absorption fine structure spectroscopy

Review of Scientific Instruments, 2023
Two extended x-ray absorption fine structure flat crystal x-ray spectrometers (EFX’s) were designed and built for high-resolution x-ray spectroscopy over a large energy range with flexible, on-shot energy dispersion calibration capabilities. The EFX uses a flat silicon [111] crystal in the reflection geometry as the energy dispersive optic covering the

Application of relativistic scattering theory of x rays to diffraction anomalous fine structure in Cu [PDF]

, 1998
We apply our recent first-principles formalism of magnetic scattering of circularly polarized x rays to a single Cu crystal. We demonstrate the ability of our formalism to interpret the crystalline environment related near-edge fine structure features in

Direct Observation of High-Temperature Polaronic Behavior In Colossal Magnetoresistive Manganites [PDF]

, 2004
The temperature dependence of the electronic and atomic structure of the colossal magnetoresistive oxides $La_{1-x}Sr_{x}MnO_{3}$ (x = 0.3, 0.4) has been studied using core and valence level photoemission, x-ray absorption and emission, and extended x ...
