Abstract
⺠Spinels nano-particles MFe2O4 (M: Co, Fe or Ni) are obtained by hydrolysis in polyol medium. ⺠Gentle reduction under hydrogen flow of spinel nano-particles yields metal and alloy nanoparticles. ⺠TEM and X-ray analysis show that CoFe2, Fe and Ni3Fe nano-particles are monocrystalline particles with size less than 160 nm. ⺠Iron with size of 150 nm presents ferromagnetic behavior. ⺠CoFe2 alloy with size of 55 nm could be considered as a superparamagnetic material.
