Monodisperse iron oxide nanoparticles
(NPs) of 4 nm were obtained trough hightemperature solution phase reaction of
iron (III) acetylacetonate with 1,2-hexadecanediol in the presence of oleic
acid and oleylamine. The as-synthesized iron oxide nanoparticles have been characterized
by X-ray diffraction, transmission electron microscopy, Mössbauer spectroscopy
and magnetic measurements. The species obtained were Fe3O4 and/or γ-
Fe2O3. These NPs are superparamagnetic
at room temperature and even though the reduced particle size they show a high
saturation magnetization (MS≈ 90
emu/g )
