Abstract

Cluster-assembled FePt:C composites were produced within the nanochannels of alumina films by combining hydrogen reduction and chemical vapor deposition (CVD). The size and the morphologies of FePt clusters inside the nanochannels and their magnetic properties were also studied. It was found that the cluster sizes were much smaller than those without carbon, when FePt clusters were synthesized with carbon and heat treated at high temperatures. It was suggested that the introduced carbon serves effectively to block the agglomeration of clusters.
