Bulk FePt/Fe3Pt nanocomposite magnets prepared by spark plasma sintering
(American Institute of Physics, 2007-04-27)
FePt/Fe3Pt bulk nanocomposite magnets have been prepared by the spark plasma sintering of chemically synthesized FePt and Fe3O4 nanoparticles under 100 MPa at 400–600 °C. It was found that the phase transition of the FePt ...
Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles
(American Institute of Physics, 2007-08-30)
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. ...
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 ...
Phase Transformation and Magnetic Hardening in Isolated FePt Nanoparticles
(IEEE, 2009-03-31)
Isolated monodisperse L1[subscript]0 FePt nanoparticles coated by carbon were obtained by adding enough surfactants that decomposed into carbon after the chemical synthesis and postannealing of the A1 FePt nanoparticles. ...

Microstructures and magnetic alignment of L10 FePt nanoparticles
(AIP, 2009)
Chemically ordered FePt nanoparticles were obtained by high temperature annealing a mixture of FePt particles with NaCl. After the NaCl was removed with de-ionized water, the transformed FePt nanoparticles were redispersed ...
