Abstract

FePt L 10 -structured clusters were synthesized by hydrogen reduction of Fe (N O3) 3 ·9 H2 O and H2 Pt Cl6 ·6 H2 O mixtures within the pores of alumina. They were released by dissolving the alumina matrix and capped with organic surfactants. After a series of chemical treatments, clusters with an average diameter of about 11 nm were precipitated. The clusters were drop casted onto ordered nanoporous arrays. Clusters reaching the bottom of the pores formed an ordered magnetic array. The corresponding magnetic film exhibits distinct anisotropic behavior caused by the external magnetic field.
