Bulk FePt/Fe3Pt nanocomposite magnets prepared by spark plasma sintering
(AIP, 2007)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 ... -
Hard magnetic FePt nanoparticles by salt-matrix annealing
(AIP, 2006)To transfer face-centered-cubic (fcc) FePt nanoparticles to the face-centered-tetragonal (fct) phase with high magnetic anisotropy, heat treatments are necessary. The heat treatments lead to agglomeration and sintering of ...
