The mechanism of the formation of lead hexaferrite
Studies of the mechanism of the formation of lead hexaferrite from its constituent oxides have been conducted. The reactions were studied by differential thermal analysis, thermogravimetric analysis, X-ray diffraction procedures and by magnetic susceptibility measurements.

SYNTHESIS AND PROPERTIES OF ACICULAR BARIUM HEXAFERRITE
The barium hexaferrite crystallizes in the hexagonal system of the magnetoplumbite type. The particles, generally prepared by solid state reactions, coprecipitation, crystallisation ion a glass or by growth under a flux, usually appear in the form of ...

Structure determination and crystal chemistry of large repeat mixed-layer hexaferrites
Hexaferrites are an important class of magnetic oxides with applications in data storage and electronics. Their crystal structures are highly modular, consisting of Fe- or Ba-rich close-packed blocks that can be stacked in different sequences to form a ...

On the Magnetization Mechanisms in Polycrystalline Hexaferrites
An attempt was made to adapt the domain-wall size model to the explanation of magnetization mechanisms in real polycrystalline hard ferrites (SrFe12O19). Some new data concerning the total anisotropy specifically for polycrystals were discussed and its value deduced from natural spin resonance measurements.
