From the combination of quantitative electron-diffraction data with X-ray- and neutron-diffraction data (so-called three-beam experiment) the partial structure factors and pair correlation functions of amorphous sputter deposited W28O72 were determin

A method has been developed to obtain quantitative electron diffraction data up to a value of Q = 20 Å−1 of the modulus of the scattering vector. The experiments were performed on a commercially available transmission electron microscope equipped

We applied grazing incidence x-ray specular and non-specular reflectivity (GIXR) and small-angle x-ray scattering (SAXS) to study the surface roughness of gold films on quartz glass substrates. Two model systems were prepared: one series of Au films

Amorphous Co100-xPx foils in the concentration range 13.4 ≤ x ≤ 26 were produced by electrodeposition. The extended X-ray absorption fine structure (EXAFS) at the phosphorous K-edge was measured in transmission mode. The phase shift was determine

Amorphous Co-P alloys with different phosphorous concentrations were produced by meltspinning, sputtering, and electrodeposition. From the combination of X-ray and neutron diffraction the atomic distances and coordination numbers for the Co-Co- and t

From an isotopic mixture of dysprosium with zero neutron scattering length and an isotopic mixture of nickel with zero neutron scattering length ribbons of the amorphous alloy Ni56 Dy44 were produced by melt-spinning and loaded with 59 at% deuterium.

Gold films were prepared by DC sputtering on quartz glass substrates under two different conditions, once in argon at 3×10−3 mbar (Au1-films), and once in residual air at 0.3 mbar (Au2-films). Specular X-ray reflection showed that the surface of t

In this paper the results of X-ray diffraction experiments of Ln-Si-Al-O-N (Ln = La, Gd, Yb) glasses are presented. Total structure factors and pair correlation functions allow the determination of the first coordination sphere of Ln atoms. The bond

Amorphous Cr80C10H10 and Cr80C10D10 films were produced by electrodeposition and investigated by X-ray and neutron small angle diffraction. The surface scattering was separated by the variation of the thickness (X-rays) and by the immersion technique
