Anomalous small-angle scattering from nanoquasicrystalline precipitates in Zr₈₀Pt₂₀ ribbons

Anomalous small-angle scattering of quasicrystals in a Zr-Pt binary alloy was examined at the Zr K absorption edge. Small differences in both density and composition were found between the quasicrystals and the amorphous matrix.

Point-focusing monochromator crystal realized by hot plastic deformation of a Ge wafer

A point-focusing Johansson monochromator crystal prepared by hot-pressing a Ge single-crystal wafer is demonstrated. By using 333 diffraction, Cu Kα radiation was focused onto a small spot.
