Doped and undoped barium hexaferrite powders (BaFe<SUB>12</SUB>O<SUB>19</SUB>, Ba<SUB>0.7</SUB>Ti<SUB>0.3</SUB>Fe<SUB>12</SUB>O<SUB>19</SUB> and Ba<SUB>0.7</SUB>La<SUB>0.3</SUB>Fe<SUB>12</SUB>O<SUB>19</SUB>) 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 La<SUP>3+</SUP> and Ti<SUP>4+</SUP> ions for the Ba<SUP>2+</SUP> ion and were accompanied by oxygen deficiency in the BaFe<SUB>12</SUB>O<SUB>19</SUB>. Coercivities (HC) from 4200 to 5100 Oe, remanences (MR) from 22 to 49 emu/g and saturation magnetizations (MS) from 41 to 73 emu/g were obtained for different samples. The obtained results were discussed in detail.
