The barium and strontium hexaferrites, BaFe12O19 and SrFe12O19, are ferrimagnetic magnetoplumbites with a hexagonal crystal structure favoring the [0001] easy magnetic direction. Commercial utilization of these materials has lead to the development of sintered polycrystalline bodies in which a substantial degree of preferred orientation or texture of the individual crystallites has been accomplished by powder pressing in a magnetic field1. The uniaxial compaction involved, however, has a randomizing tendency, one that might be avoided if the crystallite alignment process were concurrent with or following the sintering stage. Several researchers have recently achieved a high degree of preferred orientation and correspondingly enhanced magnetic properties through hot forming2–4. This paper addresses the effects of hot working upon orientation in these ferrites.
