Magnetoplumbite-type ferrite magnetic material and segment-type permanent magnet derived therefrom
A ferrite magnetic material comprising a primary phase of a magnetoplumbite-type hexagonal ferrite, the primary phase having a composition represented by formula (I), can provide improved magnetic properties in terms of the residual magnetic flux density (Br), intrinsic coercive force (iHc), squareness (Hk/iHc), and maximum energy product (B.Hmax). Therefore, a segment-type permanent magnet derived therefrom can be used in the manufacture of small type motors for automobiles, motors for electric equipments as well as for home appliances, and other devices.
