The magnetic properties of ferrites have been known to humanity since the discovery of the magnetite Fe3O4 as a natural ferrimagnetic material, which has been used in navigation compasses at the beginning of the 12 century. Furthermore, since 1930, nanoferrites have been the subject of numerous investigations, which are essentially due to their interesting magnetic and electrical properties. However, the nanosized magnetic ferrites are characterized by the superparamagnetic behavior, the higher value of electrical resistivity, saturation magnetization and permeability versus
