Abstract

The preparation processes, morphlogical, structural and magnetic properties of BaFe12-2X (CoTi) XO19 and BaFe12-2X (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.
