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 ... -
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 ... -
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 ... -
Rapid thermal annealing of FePt nanoparticles
(AIP, 2008-07-01)We report a systematic study on rapid thermal annealing (RTA) of FePt nanoparticles. FePt particles with an average size of 8 nm were synthesized by a chemical solution method, and then annealed using RTA and conventional ... -
Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles
(AIP, 2007)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. ...
