AB  - Structural and electronic properties, oxidation and aging effect of electrochemically (EC) synthesized magnetite nanopowders (NPs) are studied by means of X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) and X-ray magnetic circular dichroism (XMCD). The obtained results enabled to get a direct insight into the structure and electronic properties of Fe immediate surrounding and to elucidate the influence of preparation conditions on stoichiometry of NPs and their stability in ambient conditions. All investigated NPs are produced as nonestoichiometric Fe3-delta O4 oxide phases, with the lattice constant and the Fe2+/Fe3+ ratio both in-between the values for bulk maghemite and magnetite. NPs synthesized under smaller current density (J = 200 mA/dm(2)) are more magnetite-alike, whereas larger current density (J = 1000 mA/dm(2)) has led to formation of NPs closer to maghemite. Oxidation of magnetite-like NPs is slower, although in the course of time particles agglomerate and oxide penetrates into the core. Maghemite-like NPs oxidize much faster and the oxide layer which is confined close to the particles surface protects the core from further oxidation. In all NPs the fist coordination around Fe is pretty stable against both temperature and oxidation process. The temperature change from 293 K to 20 K considerably affects the second coordination around Fe, which is most likely a consequence of the Verwey transition present in all investigated samples.

AB  - Electrochemical (EC) synthesis of magnetite (Fe3O4) nano-powders of specific characteristics is investigated in the range of current densities of J=200-1000 mA/dm(2), and temperatures of T=295-361 K. The obtained powders and their modification upon heating in air and argon atmosphere are examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmition electron microscopy (TEM), laser light scattering particle size distribution measurements, magnetic measurements by Faraday method and SQUID, and measurements of specific electrical resistivity. It has been established that structure, morphology, magnetic and electrical properties of the powders can be adjusted by using adequate EC synthesis conditions, and/or by their subsequent heating in the appropriate atmosphere. The temperature induced magnetite reordering, the magnetite to maghemite (gamma-Fe2O3), and the maghemite to haematite (alpha-Fe2O3) phase transitions were examined, too.

AB  - Nano-sized powders of iron oxides have been synthesized electrochemically at temperatures in the range of 295-361 K, and current densities in the range of 200-1000 mA dm(-2). The structure and morphology of the powders were investigated by X-ray diffraction and scanning electron and transmission electron microscopy techniques. Their infrared absorption spectra, specific heat C(p)(T) and magnetic susceptibility chi(T) temperature dependences are also determined. The obtained powders consist of two phases, each possessing distinguished characteristics: the one formed of large plates and the other of whiskers. By appropriate adjustment of the synthesis conditions, it is possible to change features and relative abundances of the two phases, and that way to control morphology and other powder properties. Relaxation and transformation of the phases under external influences was also investigated, and the optimal procedure for preparation and stabilization of iron oxide nano-sized powders with desired characteristics was established.
