INCREASED RESONANT FREQUENCY POTASSIUM-DOPED HEXAGONAL FERRITE

摘要

Disclosed herein are embodiments of an enhanced resonant frequency hexagonal ferrite material and methods of manufacturing. The hexagonal ferrite material can be Y-phase strontium hexagonal ferrite material. In some embodiments, strontium can be substituted out for a trivalent or tetravalent ion composition including potassium, thereby providing for advantageous properties.

1. A method for doping a y-phase hexagonal ferrite material with potassium, the method comprising:
providing a y-phase strontium hexagonal ferrite material; and substituting at least some of strontium with a trivalent ion composition including potassium or a tetravalent ion composition including potassium to form a high resonant frequency hexagonal ferrite, the composition being Sr2-xKxCo2-xMxFe12O22 when a trivalent ion is used for the substitution, M being any trivalent ion, and the composition being Sr2-2xK2xCo2-xNxFe12O22 when a tetravalent ion is used for the substitution, N being any tetravalent ion.
