Abstract
Official abstract text for this publication.
Disclosed herein are embodiments of an enhanced resonant frequency hexagonal ferrite material and methods of manufacturing. The hexagonal ferrite material can be Y-phase hexagonal ferrite material, such as those including strontium. In some embodiments, oxides consistent with the stoichiometry of Sr 3 Co 2 Fe 24 O 41 , SrFe 12 O 19 or CoFe 2 O 4 can be used form an enhanced hexagonal ferrite material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for incorporating additional oxides to increase the magnetic properties of a hexagonal ferrite, the method comprising: providing a y-phase hexagonal ferrite material; and incorporating an oxide consistent with the stoichiometry of Sr 3 Co 2 Fe 24 O 41 , SrFe 12 O 19 or CoFe 2 O 4 to form an enhanced hexagonal ferrite material.
