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 ...
Effect of thermal fluctuations on the recoil loops of SmCo5[subscript]/Fe nanocomposite system
(American Institute of Physics, 2009-02-13)
The correlation between the recoil loop openness and the activation volume has been studied for the SmCo5/α-Fe nanocomposite powder material prepared by mechanical alloying. The α-Fe phase content in the nanocomposite ...
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 ...
