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 ...
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. ...
Phase Transformation and Magnetic Hardening in Isolated FePt Nanoparticles
(IEEE, 2009-03-31)
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. ...
