Sažetak
γ-irradiation is an attractive and environmentally friendly technique for the synthesis of magnetic iron oxide nanoparticles at room temperature. In this work, deaerated alkaline aqueous suspensions of iron(III) chloride were irradiated in the presence of 2- propanol and a polymer stabilizer to synthesize magnetic iron oxide nanoparticles (MIONs). We studied the effect of different polymer stabilizers (DEAE-dextran, poly(ethylene oxide)) and the effect of γ-irradiation dose on the synthesis of MIONs. The magnetic properties of the samples were studied by SQUID magnetometry and 57Fe Mössbauer spectrometry, and their structural and morphological properties were analyzed by XRD and electron microscopy. The samples showed significantly different phase compositions, morphologies and exhibited superparamagnetic behavior even at very low temperatures, depending on the polymer and absorbed dose. In-field Mössbauer spectrometry showed that the samples exhibited spin-canting phenomenon, presumably at the nanoparticle surface.
