Fabrication of bulk nanocomposite magnets via severe plastic deformation and warm compaction,
(American Institute of Physics, 2010-03-10)
We demonstrate that a SmCo/FeCo based hard/soft nanocomposite material can be fabricated by distributing the soft magnetic α-Fe phase particles homogeneously in a hard magnetic SmCo phase through severe plastic deformation. ...
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 ...
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 ...
Do thermal fluctuations influence the recoil loops of nanocomposite magnets?
(American Institute of Physics, 2008-07-11)
An exchange-coupled FePt/Fe3Pt nanocomposite system with well defined hard/soft two-phase morphology was prepared by reducing chemically synthesized FePt/Fe3O4 bimagnetic nanoparticles. It was interesting to observe that ...
