Abstract

Oriented and densely dispersed L1₀-FePtCu nanoparticles have been directly synthesized by co-evaporation of Fe, Pt and Cu using rf-magnetron sputtering onto NaCl substrate kept at 563-613K without any post-deposition annealing. Under as low a substrate temperature as 563K, superlattice reflections of the L1₀ phase appeared in selected area electron diffraction pattern, while the intensity was quite weak. As the substrate temperature increased from 563K to 613K, 〈100〉 oriented growth as well as the atomic ordering were promoted, resulted in a large increase of coercivity.
