Nanocrystalline materials were investigated by perturbedγγ-angular correlation using the radioactive probe ^{111}In. For identifying local structures observed by perturbedγγ-angular correlation various supplementing experimental techniques, like X-ray diffraction, transmission electron microscopy, absorption spectroscopy, and photoluminescence spectroscopy, were applied. In nanocrystalline TiAl alloys different crystallographic structures were observed depending on the conditions of sample treatment. Nanocrystalline Ni samples show a slightly modified local magnetic field in regions adjacent to the grain boundaries. In addition, ordered grain boundary structures were observed. Ni precipitates were identified in nanocrystalline NiCu alloys by perturbed γγ-angular correlation and preparation conditions avoiding these precipitates were found. For nanocrystalline ZnO preparation conditions were found yielding In-doped particles of good crystalline quality.
