Toward self assembly of L1/sub 0/-FePt nanoparticles by sputtering

In this experiment, Fe:Cu granular precursor is first deposited; FePt:Cu granular films are successfully prepared by interlayer diffusion of the first layer of Fe:Cu precursor and a second layer of Pt. This technique provided more degree of freedom on preparation of artificially granular films. The preparation, structure, and magnetic properties of the films have been investigated.
