Nanotechnology is the study and control of matter at the nanoscale. It gives a recondite idea of new progress in many disciplines, including medicine, environmental research, and material science. Nanoparticles of ferrites have a mind-blowing significance to their substance. Nowadays, we are making materials for various applications like microwaves with the help of this technology. The magnetic characteristics and microstructure of Mg-Mn are extremely sensitive. The synthesis and characterization of Mg-Mn ferrites using diverse techniques were studied in this article. The separate researchers doped Mg-Mn ferrites with various cations, including cobalt in the case of the solution combustion approach. It rises with rising temperature and causes a low dielectric loss at high frequencies. The density of the x-ray and lattice parameters is increased in the case of the sol-gel method by doping silver in Mg-Mn ferrites. We observe that the magnetic and dielectric properties are improved with increasing cobalt concentration in the co-precipitation process used to synthesize cobalt-doped Mg-Zn ferrites. We can improve the electrical and appealing characteristics of magnesium manganese ferrite by doping with the appropriate cations
