Both magnetization and coercivity should be controlled on BaFe₁₂O₁₉ for its usage in magnetic recording. Preparation of BaFe₁₂O₁₉ was studied in citrate route by changing the kinds of iron source. Stoichiometric mixtures of iron compounds with Ba(NO₃)₂ were dissolved in distilled water. They were mixed with citric acid aqueous solution and then condensed on a hot plate to their gelatinous products. Their prefired products below 450°C were pelletized and then fired in a temperature range between 750 and 900°C. The product from iron nitrate was a mixture of α-Fe₂O₃, BaFe₂O₄ and a small amount of BaFe₁₂O₁₉. The product from Fe(acac)₃ was pure BaFe₁₂O₁₉ fine powder with a crystallite size of < 90 nm. The fine powdered product at 850°C had a saturation magnetization of 58.5 emu·g^-1 and a coercivity of 5.5 kÖe.
