- The presented study compares magnetic properties of Ni-doped magnetites $Ni_{0.5}^{2+}Fe_{0.5}^{2+}Fe_{2}^{3+}O_{4}$ to magnetite $(Fe_3O_4)$ sample. Physicochemical properties of materials were registered by means of X-ray powder diffraction, Mössbauer spectroscopy, saturation magnetization and physical properties measurement systems. It was obtained that used preparation procedures lead to synthesis of single phase spinel materials with close nanodimensional size about 8-12 nm. Mechanochemically synthesized sample shows better magnetic properties as lower blocking temperature of superparamagnetic state and minimal coercivity in comparison to other studied materials.
