To reveal the intrinsic mechanism of Mn x Zn 1‐ x Fe 2 O 4 ( x =0.2, 0.4, 0.6, 0.8 and 1) nanoferrite with various content of Mn/Zn are prepared by hydrothermal method. The physical properties are characterized by X‐ray diffraction (XRD), Fourier transformed infrared spectrometer (FTIR), Transmission electronic microscope (TEM), Energy Dispersion Spectrum (EDS) and Vibrating Sample Magnetometer (VSM). The phase structure, lattice parameters, and magnetic properties have been investigated based on the entire cation distribution with enhancement of the Mn 2+ . The XRD and FTIR analysis indicate that the samples have cubic spinel ferrite structure, the lattice constant a t and crystallite size D increase with enhancement of Mn content. The VSM plots demonstrate that the Mn 0.6 Zn 0.4 Fe 2 O 4 sample has the largest saturation magnetization value (77 emu/g). These results indicate that a fine tuning of Mn 2+ content can adjust the micro‐structure and magnetic properties of Mn x Zn 1‐ x Fe 2 O 4 .
