In this work, the cubic spinel manganese‐zinc ferrite nanoparticle is synthesized by the sol–gel auto combustion method. It is the simple chemical route and low‐cost method for the formation of manganese zinc ferrite nanoparticles. Structural and morphological studies of the synthesized manganese‐zinc ferrite nanoparticles are done by X‐ray diffraction, Fourier transform infrared spectroscopy (FTIR), and scanning electron microsccopy (SEM). The X‐ray diffraction results indicate that the ferrite sample has a cubic spinel type structure with Fd3m space group. The average crystallite size of the synthesized manganese zinc ferrite nanoparticles is found to be 34 nm as determined by Debye–Scherrer equation. Two well‐known absorption bands at 467 and 558 cm −1 , in FTIR spectroscopy data also confirm the cubic spinel structure in the prepared samples. Morphological studies by SEM exposed formation of largely agglomerated and well‐defined nanoparticles of the sample. From the magnetization data, parameters like magnetization, coercivity, remanance magnetization, and squareness ratio are calculated.
