Electromagnetic Properties of Substituted Barium Hexaferrites

Abstract

Substituted M-type ferrite BaFe 12-2x (Me 1 Me 2 ) x O 19 , 0 ≤ x ≤ 0.6 was prepared by both mechanical alloying and precursor method, where Me 1 = Co, Ni, Zn, Sn and Me2 =Ru, Ti, Zr, Sn.Magnetic phase purity, change of saturation polarization, Curie temperature, coercivity and magnetic susceptibility was studied as function of x.Attention was focused to results obtained for (NiRu) x , (ZnRu) x , and (SnRu) x mixtures with low doping ratio x.
