Bimagnetic nanoparticles with enhanced exchange coupling and energy products
(American Institute of Physics, 2009-01-06)
Bimagnetic FePt/Fe3O4 nanoparticles with core/shell or heterodimer structure have been prepared using a sequential synthetic method. The dimension of both FePt and Fe3O4 was tuned by varying the synthesis parameters. The ...
Bulk FePt-based nanocomposite magnets with enhanced exchange coupling
(American Institute of Physics, 2007-07-23)
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 ...
