Tuning the Magnetic Properties of M-type Hexaferrites

Tuning the Magnetic Properties of M-type Hexaferrites

S.H. Mahmood, I. Bsoul

In this chapter, common experimental techniques and preparation conditions adopted for the synthesis of M-type hexaferrites and their influence on the magnetic properties are briefly reviewed. The effects of various strategies of cationic substitutions on the properties of the hexaferrites are addressed. Further, our synthesis and findings on Co-Ti substituted hexaferrites are presented. It was found that Co-Ti substitution results in improving the saturation magnetization, and reducing the coercivity down to values favorable for high- density magnetic recording. Also, evidence of inter-particle interactions in the particulate samples was observed.
