Development and Preparation Processes of Barium Ferrite Particles for Magnetic Information Storage

抄録

The preparation processes, morphlogical, structural and magnetic properties of BaFe_12-2X (CoTi) _XO₁₉ and BaFe_12-2X (CoSn) _XO₁₉ fine particles, prepared by chemical coprecipitation, synthesis from salt melts and glass crystallization method were investigated. The correlation between the magnetic properties, the particle morphology and the degrees of Co Ti and Co Sn substitutions of Ba ferrite particles were studied. These substituted Ba ferrite particulate media are of great interest for high density magnetic information storage.
