Abstract

Doped and undoped barium hexaferrite powders (BaFe₁₂O₁₉, Ba_0.7Ti_0.3Fe₁₂O₁₉ and Ba_0.7La_0.3Fe₁₂O₁₉) were produced by the sol-gel method. The effects of substituting elements were studied in terms of the magnetic properties of barium hexaferrite powders. The magnetic properties were remarkably changed by the substitution of La³⁺ and Ti⁴⁺ ions for the Ba²⁺ ion and were accompanied by oxygen deficiency in the BaFe₁₂O₁₉. Coercivities (H_C) from 4200 to 5100 Oe, remanences (M_R) from 22 to 49 emu/g and saturation magnetizations (M_S) from 41 to 73 emu/g were obtained for different samples. The obtained results were discussed in detail.
