Patent ID: 8273407

Claim:
A method of fabricating a thin film of magnetic nanocomposite particles comprising: depositing isolated clusters of magnetic nanoparticles onto a substrate surface via a thin film deposition technique that is compatible with integrated circuit (IC) fabrication techniques; and subsequently aggregating said isolated clusters of magnetic nanoparticles; and subsequently coating said isolated clusters of magnetic nanoparticles with an insulator coating; and wherein said isolated clusters of magnetic nanoparticles have a dimension in the range between 1 and 300 nanometers and are separated from each other by a distance in the range between 1 and 50 nanometers; and wherein said substrate surface comprises a nucleating layer and wherein said deposition of isolated clusters of magnetic nanoparticles onto said nucleating layer is truncated at a point where clusters formed around nucleation sites are stopped before the clusters coalesce.
