MICROWAVE FERRITE MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Disclosed herein are a microwave ferrite material, a preparation method therefor and an application thereof. According to the microwave ferrite material, Y and Zr are partially replaced with Ca, Fe is partially replaced with Al, and the properties of Ca, Y, Zr, V, Al, and Fe are utilized to make the obtained microwave ferrite material have a proper saturation magnetization, ferromagnetic resonance linewidth, and Curie temperature. At the same time, by using a specific amount of V and Al to cooperatively add, it is ensured that the obtained microwave ferrite material has a loss of no more than 0.5 dB within a temperature range of −55° C. to 125° C. and a frequency band range of 700 MHz to 5 GHz, so that the microwave ferrite material has the characteristics of low loss, high Curie temperature, and low magnetic moment, and the requirements of miniaturization, low loss, and wide frequency of an isolator and a circulator can be realized.
