MODIFIED Z-TYPE HEXAGONAL FERRITE MATERIALS WITH ENHANCED RESONANT FREQUENCY |
| 摘要 |
Disclosed herein are embodiments of modified z-type hexagonal ferrite materials having improved properties that are advantageous for radiofrequency applications, in particular high frequency ranges for antennas and other devices. Atomic substitution of strontium, aluminum, potassium, and trivalent ions can be used to replace certain atoms in the ferrite crystal structure to improve loss factor at high frequencies. |

1. A high resonant-frequency material composition comprising:
an enhanced z-type hexagonal ferrite having some barium atoms substituted for strontium atoms and some iron atoms substituted for aluminum atoms, the enhanced z-type hexagonal ferrite having a formula Ba3-xSrxCo2Fe24-yAlyO41 and having a resonant frequency of over about 500 MHz. |
