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 ...
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 ...
High thermal stability of carbon-coated L10-FePt nanoparticles prepared by salt-matrix annealing
(AIP, 2008)
Monodisperse L10-FePt nanoparticles with size ranging from 3 to 8 nm were prepared by the salt-matrix annealing method. It was observed that the annealed particles have high thermal stability—no sintering occurred even ...
