Claim Text:
1. A method of making a bulk magnetic nanocomposite comprising: a) providing a first powder comprising at least one hard magnetic component having an anisotropic field greater than or equal to about 5000 Oe; b) providing a second powder comprising at least one soft magnetic component having an anisotropic field less than or equal to about 1000 Oe; c) combining said first and second powders to form a mixture; d) processing said mixture by plastically deforming said mixture to form a processed mixture having at least a one thousand time size reduction of soft magnetic component inclusions; and e) warm compacting said processed mixture to form a bulk magnetic nanocomposite, comprising: a matrix comprising said at least one hard magnetic component; and a plurality of particles comprising said at least one soft magnetic component; wherein said plurality of particles of said soft magnetic component are no larger than about 20 nm in at least one dimension and the plurality of particles of said soft magnetic component are homogenously distributed in the matrix.
