摘要：
Minute crystals of barium hexaferrite containing small amounts of Ti4+ and Co2+ ions have been prepared by the slow cooling method from a high-temperature solution of the Na2O-B2O2 system. Magnetic properties (coercivity, saturation magnetization, remanence) and lattice parameters were measured as a function of Ti4+ and Co2+ concentration in the crystals. The site preferences for Ti4+ and Co2+ ions are also discussed.
