چکیده انگلیسی
Crystallographic, microstructural and magnetic properties of ZnFe2O4 nanoparticles synthesized by precipitation from non-aqueous solutions have been studied in the work. The transmission electron microscopy studies reveal particle sizes â¼5 nm for the as-prepared particles which increase up to â¼25 nm upon annealing at 500 °C. Characteristic magnetic parameters of the particles including average magnetic moment of an individual nanoparticle and effective anisotropy constant have been determined by means of the quasistatic magnetic measurements. The specific loss power which is released on the exposure of an ensemble of synthesized particles to an electromagnetic field is calculated and measured experimentally. It is shown that the particles demonstrate high heating efficiency in AC magnetic fields, which is enough for their use in medical applications.
