Abstract

Magnetni nanodelci se v zadnjih letih vedno bolj uporabljajo na številnih znanstvenih področjih zaradi njihovih edinstvenih lasnosti, ki so povezane z njihovo izredno majhno velikostjo. Med sabo združujejo in povezujejo različne znanstvene discipline, kot so medicina, kemija, biologija, fizika in mnoge druge. V diplomskem delu je prikazana sinteza maghemita γ-Fe2O3 z različnimi razmerji Fe2+ in Fe3+ ionov (1:1, 1:2, 2:1, 1:3 in 3:1). Proučili smo vpliv zunanjega magnetnega polja na magnetne lastnosti sintetiziranih magnetnih nanodelcev (MNPs) različnih množinskih razmerij Fe2+ in Fe3+ ionov. Sintetizirane MNPs različnih množinskih razmerij Fe2+ in Fe3+ ionov smo okarakterizirali s Fourierovo transformirano infrardečo spketroskopijo (FTIR) in termogravimetrično analizo (TGA). Magnetne lastnosti sintetiziranih MNPs so bile določene z meritvami magnetne polarizacije v izmeničnem magnetnem polju.

Secondary title: The influence of the ratio of Fe 2+ and Fe 3+ ions on the magnetic properties of magnetic nanoparticles
Secondary abstract: Magnetic nanoparticles have been increasingly used in many scientific fields in recent years due to their unique hair-like properties, which are linked to their extremely small size. They bring together and link different scientific disciplines such as medicine, chemistry, biology, physics and many others. In this thesis, the synthesis of γ-Fe2O3 maghemite with different Fe2+ and Fe3+ ion ratios (1:1, 1:2, 2:1, 1:3 and 3:1) is presented. The influence of an external magnetic field on the magnetic properties of the synthesized magnetic nanoparticles (MNPs) with different Fe2+ and Fe3+ ion mass ratios has been investigated. The synthesized MNPs of different mass ratios of Fe2+ and Fe3+ ions were characterized by Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The magnetic properties of the synthesized MNPs were determined by magnetic polarization measurements in an alternating magnetic field.
