Abstract
Fe-Cu nanoparticles have been prepared by sputtering and subsequent in-flight sintering. Particles deposited onto amorphous carbon are examined by electron diffraction, energy dispersive x-ray line-scans and electron energy loss spectroscopy using high resolution transmission electron microscopy. The results show that non-sintered particles form a metastable Fe-Cu alloy, whereas the sintered particles undergo a spinoidal decomposition leading to an iron-rich core and a Cu-rich shell. The investigations are carried out on particles of various sizes ranging from 5-50 nm. Within this size range, the sintered particles show similar compositional properties.
