Local atomic structure of martensiticNi2+xMn1−xGa: An EXAFS study

Study of light-induced vector changes in the local atomic structure of As–Se glasses by EXAFS

We have observed light-induced vector changes in the local structure of As–Se glasses using extended X-ray absorption fine structure (EXAFS) experiments with in situ laser illumination. Local structure around As and Se atoms was determined for as-prepared as well as annealed a-As40Se60 films, which were exposed to bandgap light of polarization parallel and perpendicular to that of the X-rays. F...

Local Structure of Ion-Bombarded α-SiC Analyzed by EXAFS

X-ray absorption spectroscopy on the Si k-edge was performed on a-Sic (6H) to monitor the evolution of the local structure around the Si atoms after ion bombardment. The samples were irradiated by 50 keV Na ions at fluences of 10" 10" ions/cma at a temperature of 80 K. EXAFS analysis clearly reveals that the hetero-atomic short range order of the crystalline matrix is almost completely conserve...

EXAFS study of the local structure of crystalline and nanocrystalline Y2O3 using evolutionary algorithm method

Temperature-dependent local structure and lattice dynamics of yttria (Y2O3) were studied by X-ray absorption spectroscopy. Novel method, which combines the reverse Monte Carlo and evolutionary algorithm techniques, was applied for the analysis of extended X-ray absorption fine structure at the Y K-edge. This approach allowed us to reconstruct 3D atomic structure models of crystalline and nanocr...
