Bulk FePt-based nanocomposite magnets with enhanced exchange coupling
(AIP, 2007)
High density bulk FePt/Fe3Pt nanocomposite magnets have been prepared by high-pressure warm compaction of chemically synthesized FePt and Fe3O4 nanoparticles. It is found that the density increases with the compaction ...
Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles
(AIP, 2007)
FePt nanoparticles with a size of 3 nm and thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles were prepared by chemical synthesis and a salt-matrix annealing technique. ...
