MAGNETODIELECTRIC Y-PHASE STRONTIUM HEXAGONAL FERRITE MATERIALS FORMED BY SODIUM SUBSTITUTION

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, sodium can be added into the crystal structure of the hexagonal ferrite material in order to achieve high resonance frequencies while maintaining high permeability.
