Small angle scattering investigation of nanostructured binary Au-Fe alloys

Small Angle Neutron Scattering measurements have been performed on granular materials with composition Au100-xFex (x=20, 27, 30, 38) obtained in the form of melt spun ribbons and of co-sputtered thin films. The as cast melt spun ribbons, show only the presence of nearly atomic iron precipitates, subsequent thermal treatments induce the formation of lamellar-shaped iron precipitates. In the co-sputtered films the iron nanoparticles are non-uniformly distributed in the Au matrix
