Abstract: The magnetic properties of magnesium–iron spinel (MgFe$_{2}$O$_{4}$) powdered nanoparticles obtained by glycine–nitrate synthesis are investigated by X-ray phase analysis and the NMR method. According to the results of X-ray phase analysis, the average size of the crystalline part of nanoparticles of the powder under investigation is 45 $\pm$ 4 nm. Magnetization $J$ is determined using the formula $J=(B/\mu_{0})-H$, where $B$ and $H$ are the induction and strength of the magnetic field in the sample, which are measured by the NMR method. The magnetic characteristics of MgFe$_{2}$O$_{4}$ are as follows: specific saturation magnetization $J_{sat}$ = 17.52 A m$^2$/kg, specific residual magnetization $J_r$ = 5.73 A m$^2$/kg, coercive force $H_c$ = 4600 A/m, and magnetic moment $P_{sat}$ = 371 $\times$ 10$^{-20}$ A m$^2$ in the magnetic saturation state and $P_r$ = 121 $\times$ 10$^{-20}$ A m$^2$ in the residual magnetization state.
Keywords: Coercive Force, Magnetic Characteristic, Magnetic Fluid, Coherent Scattering Region, Residual Magnetization.
