MGFe2O4-containing nanopowders were synthesized by the hydrothermal method. Phase composition and particle size were estimated by XRD analysis and by the electronic microscopy. Magnetic properties measurements showed the formed MGFe2O4 nanoparticles are in superparamagnetic state. The saturation magnetization is determined, MS = 8.7 emu/g.
Keywords: hydrothermal synthesis, spinel, nanoparticles, magnetic susceptibility, saturation magnetization, superparamagnetism.
