Magnetic characteristics of MgFe$_{2}$O$_{4}$-containing nanopowders prepared by the hydrothermal method

MgFe$_{2}$O$_{4}$-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 MgFe$_{2}$O$_{4}$ nanoparticles are in superparamagnetic state. The saturation magnetization is determined, MS = 8.7 emu/g.
