FeCo nanoparticles coated with (Fe,Co)(3)O-4 (magnetite doped with
cobalt) were synthesized by the proteic sol-gel chemical route. The
synthesized materials were characterized by Thermogravimetry (TG), X-Ray
Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission
Electron Microscopy (TEM), vibrating-sample magnetometer (VSM) and
Mossbauer spectroscopy (MS). The results show that the increase in
temperature and the choice of the correct air/N-2 flow directly
influence on the final physical-chemical properties of the
nanocomposite. The SEM and TEM images confirmed that a thin layer of
oxide was formed on the alloy, indicating that it was obtained a
self-assembled FeCo-(Fe,Co)(3)O(4 )nanocomposites. In addition, the VSM
results show that a possible exchange-spring coupling in magnetic
FeCo-(Fe,Co)(3)O-4 nanoparticles occurred with high saturation
magnetization from FeCo alloy and high coercivity from (Fe,Co)(3)O-4.
The rotary oven allows the uniform contact of the powder with the
atmosphere of synthesis during the different oxidation-reduction steps,
generating more homogeneous particles.
