ABSTRACT:
A single layer film is deposited onto a substrate at room temperature from two sources, one source being a magnetic material, the other being a non-magnetic or weakly-magnetic material. The film is annealed for predetermined time in order to induce phase separation between the magnetic clusters and the non-magnetic matrix, and to form stable clusters of a size such that each magnetic particle, or cluster, comprises a single domain and has no dimensions greater than the mean free path within the particle.
