heal.abstractHydrolysis of the new metallorganic precursor Fe(OBut)2-(THF)2 followed by ultrasound and thermal treatment yielded either nanoparticles of γ-Fe2O3 or Fe3O4, depending on the process conditions. The samples have been characterised by X-ray powder diffraction, TEM, SEM, M?ssbauer spectroscopy and magnetization measurements. The maghemite nanoparticles (9±2 nm) are superparamagnetic and form unique needle-like assemblies of nanoparticle arrays. The nanoparticles of Fe3O4 (19±2 nm) form plate-like aggregates about 10 μm thick.en
