摘要：
Barium ferrite BaFe12O19 and its substituted derivatives BaFe9.6Co0.8Ti0.8M0.8O19 (M = Cu,Zn,Cr,AI,Sn,Sb) have been prepared from chemical coprecipitated carbonate precursor Powders of the samples show a hexagonal fine platelet structure and a narrow particle size distribution. Hysteresis loop measurements prove that the coercivity suitable for magnetic recording can be obtained in this new Co-Ti-M series. (C) 2000 Elsevier Science S.A. ALI rights reserved.
