Ni-Zn ferrites are magnetic ceramics that have been widely used on the fabrication of electrical and electronic components. Such materials have been studied for many years by several researchers and their magnetic and electrical properties have been assessed in relation to many factors, such as chemical composition, fabrication methods, and microstructure. This work makes a review of the main factors influencing the properties of Ni-Zn ferrites. It is emphasized the magnetic permeability and dielectric constant, as well as the characteristics of the conventional ceramic method on the fabrication of these ferrites.
