The nanosized ZnFe2O4 material was synthesized using the coprecipitation method from Zn2+ and Fe3+ cations in a boiling aqueous medium. The results of TG/DSC, XRD, SEM, TEM and VSM analysis show that the ZnFe2O4 material prepared after annealing at 600 °C had tetragonal structure, a size of 20 – 50 nm, Hc < 70 Oe, Mr < 0.5 emu/g and Ms ~ 2.5 emu/g.
Keywords: sol-gel synthesis, nanopowders, zinc ferrite, magnetic properties.
