In this paper, spherical Fe3O4@OA nanoparticles were prepared via solvothermal method, in which iron sulphate, sodium hydroxide and oleic acid were used as precursors. The main idea of this research was to develop the method for preparation of nanoparticles with magnetic properties suitable for application in magnetic hyperthermia. We have tried to tailor size, shape and the degree of interparticle interactions by varying experimental conditions during the synthesis route. Obtained samples were structurally and magnetically characterized by means of different experimental probes such as: X-ray diffraction, SQUID magnetometry, FTIR and Mossbauer spectroscopy. Structural characterization asserts that the obtained phase is magnetite, Fe3O4, while FTIR spectra support the presence of oleic acid coating on the particle surface. Detailed magnetic characterization done by SQUID measurements and Mossbauer spectroscopy confirmed the presence of the strong and weak interactions in the nanoparticles system, depending on the synthesis conditions.11th Conference for Young Scientists in Ceramics (SM-2015, and ESR Workshop, COST MP1208) : programme and the book of abstracts, October 21-24, Novi Sa
