Abstract : In order for the nanomaterials to be utilized, it is vital to be able to control the structural and magnetic properties of the Mn-Zn-ferrites nanocomposite by sol-gel nanocomposite generated by sol – gel method at 650, 750, and 850 oC. An examination into the possibility of producing the Mn-Zn-ferrites (NPs) by sol-gel as prospective structure-tunable nanomaterials is described in this report. X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), Fourier-transform infrared (FTIR) spectroscopy and Vibrating Sample Magnetometer (VSM) analysis were used to characterize the structural and magnetic properties of the Mn-Zn-ferrites by sol-gel. The crystallite sizes range from 15 to 18 nm, and the cubic structure of the ferrites shows up in XRD (NPs). Nanoparticles having a particle size of 27.77 to 72.04 nm were found in the produced Mn-Zn-ferrites. In the case of the Mn-Zn-ferrites, prominent FT-IR absorption peaks at 400 and 500 cm-1 indicated the presence of Fe-O, Mn-O, and Zn-O vibrational bands. Results from the VSM demonstrated that the magnetic nature of materials changed dramatically from pristine as magnetization rose and coercivity decreased with Mn-Zn-ferrites nanoparticles. Finally, an optimal magnetic parameter value (Ms =0.80 emu/g and Hc =75 Oe) at (850) oC was obtained from the data.
