Cobalt films of different average thickness ( t Co =0.15–4.8 nm) have been deposited on amorphous alumina (a-Al 2 O 3 ) at different temperatures ( T s =130–600°C), with the aim of forming Co nanoparticles of well-defined size and shape. Two dep

The crystalline structure of Co clusters embedded in an amorphous Al2O3 matrix was studied by transmission electron microscopy (TEM) and electron diffraction (TED). In the first stage of the growth a metastable structure (body-centred-cubic) is obser
