Abstract

MAGNETITE NANOPARTICLES have been synthesized using SONOELECTROOXIDATION of iron plate in an aqueous solution of electrolyte containing THIOUREA as organic stabilizer. The effect of applied CURRENT on structural and magnetic properties of nanoparticles was investigated. The particles structure was characterized using XRD, and SEM.Room-temperature MAGNETIZATION curves of the samples obtained using a VSM. In order to study the stoichiometric property of the MAGNETITE NANOPARTICLES, Mössbauer spectra in transmission geometry were recorded for all samples. The X-ray patterns showed that the products have cubic spinel structure with space group. The SEM images showed that the particles with sizes in the range 25 to 50 nm depending on the applied CURRENT are grown. The room-temperature VSM results showed that all of the samples are magnetically soft and their specific MAGNETIZATION depends on the mean particle size. Mössbauer spectra are well fitted with two magnetic sextets sub-spectra corresponding to Fe3+ions at A sites (tetrahedral coordination) and Fe2.5+ ions at B sites (octahedral coordination) associated with magnetite structure.The chemical formula of samples was obtained by taking in to account the deficit of iron in their structure.
