| 摘 要： | 吸波材料是指能够吸收衰减入射的电磁波,并将其电磁能转换成热能而耗散掉或使电磁波因干涉而消失的一类功能材料,磁性吸波材料是目前研究和应用最多的一类。在磁性吸波材料中掺入微量稀土元素能很好地提高材料的吸波特性。本文综述了稀土磁性吸波材料的研究现状,阐述了稀土磁性吸波材料的吸波机理和制备方法,提出了稀土磁性吸波材料的研究方向。

| Abstract: | Electromagnetic wave absorbing material is a type of function material which can absorb and attenuate the electromagnetic wave, and change the electromagnetic wave energy into heat energy or make the electromagnetic wave vanish by the way of interference. It has been researched and applied mostly. The absorbing properties can be greatly improved by adding trace rare earth el- ement to the electromagnetic absorbing material. In this paper the present situation and the latest development of the rare earth magnetic absorbing materials were reviewed. The absorbing mechanism and processing method were introduced. Finally, the development trend of the rare earth magnetic absorbing materials was predicted. |
