Microwave ferrite material as well as preparation method and application thereof
The invention relates to a microwave ferrite material and a preparation method and application thereof. According to the microwave ferrite material, Y, Zr and V are partially replaced with Ca, Fe is partially replaced with Al, the obtained microwave ferrite material has proper saturation magnetization, ferromagnetic resonance line width and Curie temperature by means of the properties of Ca, Y, Zr, V, Al and Fe, meanwhile, the specific amount of V and Al are synergistically added, the loss of the microwave ferrite material does not exceed 0.5 dB within the temperature range of -55 DEG C to 125 DEG C and the 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 broadband of isolators and circulators can be met.
本发明涉及一种微波铁氧体材料及其制备方法与应用，所述微波铁氧体材料通过Ca部分替换Y，Zr、V以及Al部分替换Fe，利用Ca、Y、Zr、V、Al以及Fe的性质，使所得微波铁氧体材料具有合适的饱和磁化强度、铁磁共振线宽和居里温度，同时利用V与Al的特定量协同添加，保证了所得微波铁氧体材料在‑55℃至125℃温度范围以及700MHz‑5GHz的频段范围内，损耗不超过0.5dB，使微波铁氧体材料具有低损耗、高居里温度且低磁矩的特点，可以实现隔离器及环形器的小型化、低损耗以及宽频化的要求。
