摘要：
By using high-resolution transmission electron microscopy the formation of the L1(0) phase in Fe-Pt multilayer can be studied in-situ during annealing. The formation of L1(0)-FePt nuclei starts in the Pt layers by diffusion of Fe into the Pt layers. During annealing the L1(0)-FePt nuclei grow in size and expand over the whole film. By using electron lithography patterned L1(0)-Fe54Pt46 nanostructures have been produced. Below a critical dot thickness during post-annealing at high temperatures the dots split into an accumulation of isolated (single-domain) particles of irregular shape resulting in large coercivities of mu H-0(c) = 2.4 T.
