摘要：
Ferromagnetic nanocrystalline materials, consisting of Ni and Pd-Fe, are investigated on an atomic scale by perturbed γγ-angular correlation spectroscopy, complemented by X-ray diffraction and energy dispersive X-ray spectroscopy. Nanocrystalline Ni was produced by pulsed electrodeposition and simultaneously doped with 111In probe atoms. Besides the local magnetic field known from polycrystalline Ni, a second component is detected, which is attributed to a magnetic perturbation due to grain boundaries. During ball-milling of Pd, a Pd0.70Fe0.30 solid solution caused by Fe impurities is obtained, which is ferromagnetic at room temperature. Annealing between 600 K and 1000 K transforms this solid solution into the compound γ2-Pd3Fe.
