Cu {ital K}-edge extended x-ray-absorption fine-structure (EXAFS) measurements of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}h({delta}=0.05) at atmospheric pressure and at 3.4, 11.4, 31.8, and 65 kbar are presented. The experiments were performed isoth

Nanostructures have become a major field in a material science. With molecular beam epitaxy it is possible to engineer multilayers with unusual anisotropic properties and metastable strucutres. For ultrathin films, or particles of small size, the coo

Anomalous dispersion effects distort the EXAFS interference functions obtained at glancing angles of incidence. It is shown that the distortions in the amplitude and phase shift are strongly dependent on the thickness of the sample layer in a multila

The XANES of a multilayer system obtained in the total reflection geometry can be distorted due to anomalous dispersion effects in the sample layers and in adjacent media. The former plays a negligible role in ultrathin film cases. The latter, caused

A single-scattering model is found to explain the near-edge structure in the X-ray absorption spectra of crystalline solids remarkably accurately. Resonances in the X-ray absorption are interpreted as constructive interference at the excitation site,

The X-ray absorption fine structure (XAFS) of amorphous germanium under pressures ranging from 0.0 to 8.9 GPa is investigated. Contrary to some reports from the literature we cannot find a transition to crystalline germanium at about 6 GPa. Analysis
X-ray absorption near-edge spectroscopy (XANES) is used to study the N environment in bulk GaN and in GaN{y}As{1-y} epilayers on GaAs (001), for y \~5%. Density-functional optimized structures were used to predict XANES via multiple-scattering theory

A design of a total electron yield detector used in glancing-incidence EXAFS is described. This design allows the simultaneous detection of fluorescence and reflectivity. It also permits selecting different angles of the incident X-ray beam relative

A clear understanding of the mechanisms of interfacial magnetic anisotropy rests on the structural characterisation of magnetic multilayers which, typically, consist of two ferromagnetically coupled (F) layers separated by a non-magnetic spacer layer

For some time, it has been recognized that the structure of silicate liquids has a great bearing on such magma properties as viscosity, diffusivity, and thermal expansion and on the extrapolation of thermodynamic quantities outside of the experimenta
