Abstract

It is investigated the processes occurring at the atomic level near the surface of the ferrite Mn0.6Zn0.3Co0.05Fe2.05O4, obtained in different conditions - standard and special atmospheres. The proposed method of Zn-saturation of the surface layers of ferrite partially recovers not only the chemical composition but also the magnetic structure near the surface of the ferrite products
