Highly-ordered, three-dimensional superlattices were self-assembled from dodecanethiol-ligated gold nanocrystals using a simple drop-drying technique. The superlattices had the shape of truncated pyramids (frustums) and reached lateral dimensions of several micrometers. The formation and thermal stability were studied by grazing-incidence small-angle x-ray scattering. We found that the superlattice frustums adopt a

A dedicated in-vacuum X-ray detector based on the hybrid pixel PILATUS 1M detector has been installed at the four-crystal monochromator beamline of the PTB at the electron storage ring BESSY II in Berlin, Germany. Owing to its windowless operation, the detector can be used in the entire photon energy range of the beamline from 10 keV down to 1.75 keV for small-angle X-ray scattering (SAXS) experiments and anomalous SAXS at absorption edges of light elements. The radiometric and geometric properties of the detector such as quantum efficiency, pixel pitch and module alignment have been determined with low uncertainties. The first grazing-incidence SAXS results demonstrate the superior resolution in momentum transfer achievable at low photon energies.

Grazing-incidence small-angle X-ray scattering is reported from nanoclusters in superparamagnetic (SPM) polycrystalline Co separated by Au. The self-organization of the Co nanoclusters is in the form of nanopillar-like structures with high perpendicular magnetic anisotropy. A distinct signature of regular near-neighbour ordering is observed, which is commonly observed in patterned nanostructures. The estimated cluster sizes corroborate with those estimated from their magnetic field response. Most significantly, the SPM limit for these clusters can be raised to above room temperature (∼325 K) with an increase in the vertical correlation of the nanopillars. The slow response time of these uniform nanomagnetic grains (with respect to a 10 kHz AC field) suggests their possible usage as potential magnetic storage devices in the form of three-dimensional nanopillars.
