Focusing on the magnetoplumbite (M-type) hexaferrites Mahmood and Abu-Aljarayesh summarize the basic concepts of magnetics, and magnetic properties pertinent to permanent magnetic materials, the importance of these materials in terms of their market share and versatility of practical use, synthesis techniques, and routes for modifying and tuning their magnetic properties.
The diffraction patterns of the samples showed characteristic diffraction peaks ascribed to the M- type Sr-ferrite structure having point group p63/mmc.This indicates that the crystal structure did not transform and remained hexagonal magnetoplumbite even after substitution with cobalt up to 12 %.
It has been observed that the complex dielectric constants are decreasing with increasing frequency for all samples annealed at 1100[degrees]C that shows a normal dielectric behavior of magnetoplumbite structure.
Among all the ferrite material, spinel and magnetoplumbite ferrite stand out.
Relationship to other speci es: A member of the magnetoplumbite group.
