Abstract

Using a double-grow discharge cluster source system Fe and Ni clusters have been produced and deposited simultaneously on a substrate. A mixture of Fe and Ni clusters have been obtained with inserting separation plates between two grow discharge rooms and in the center of a growth tube, where partially alloyed cluster assemblies are formed. Fe-Ni alloy cluster assemblies have been obtained without inserting the separation plate. This alloying behavior is different from core-shell cluster formation in simultaneous deposition of Co and Si clusters, and Fe and Si clusters without inserting the separate plate. The present results suggest that structure and morphology of composite clusters strongly depends on the surface energy and degree of oxidation of elemental clusters.
