Phase Transformation and Magnetic Hardening in Isolated FePt Nanoparticles
Isolated monodisperse L1[subscript]0 FePt nanoparticles coated by carbon were obtained by adding enough surfactants that decomposed into carbon after the chemical synthesis and postannealing of the A1 FePt nanoparticles. ...
Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles
(American Institute of Physics, 2007-08-30)
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. ...
Shape control of FePt nanocrystals
(American Institute of Physics, 2009-04-06)
: FePt nanocrystals were prepared by simultaneous reduction of platinum acetylacetonate and thermal decomposition of iron pentacarbonyl in properly chosen solvents/surfactants. A variety of FePt nanocrystals, including ...
