| 摘 要： | 采用高分子凝胶法制备了Ni0．5Zn0．5La0．05Fe1.95O4铁氧体。当煅烧温度为600℃时，立方晶系尖晶石结构的Ni0．5Zn0．5La0．05Fe1.95O4相初步形成。掺杂稀土La后，Ni0．5Zn0．5La0．05Fe1.95O4铁氧体的吸波性能显著提高，吸收峰向高频移动，其电磁波反射率小于～10dB的频宽可达2．7GHz，最小反射率为-15．6dB。

| Abstract: | Ni0.5Zn0.5La0.05Fe1.95O4 ferrite was prepared using polyacrylamide gel method. A pure spinel strueture of Ni0.5Zn0.5La0.05Fe1.95O4 formed at 600 ℃. The microwave absorbing property was better for the specimen of Ni0.5Zn0.5La0.05Fe1.95O4 ferrite than the no doped Ni--Zn ferrite specimen. Its absorbing peak moved to higher frenquency. Its minimum reflection loss was -15.6 dB with a -10 dE bandwidth o- ver the extended frequency range of 2.7 GHz. |
