制备研究了钴铁磁体/碳和镍钴铜铁磁体/碳复合纳米材料，测试并根据朗伯-比尔定律计算了在紫外/可见光(200~800 nm)和红外波段(2.5~25 μm)的质量消光系数，结果如下：铁磁体/碳复合材料焙烧后红外消光性能都有所提高，镍钴铜铁磁体/碳质量消光系数能达到0.36 m²·g^-1，在3~16 μm波段大于0.15 m²·g^-1。镍钴铜铁磁体/碳与乙炔黑混合比为5:1时，质量消光系数达到1.25 m²·g^-1，在3~5 μm和8~14 μm均高于0.90 m²·g^-1。在紫外/可见光波段，铁磁体/碳复合材料都达到了良好的消光效果。探讨了材料在紫外/可见光和红外波段的主要作用机理。 采用“弓形法”测试2~18 GHz波段反射率，结果表明：碳纤维在加入铁磁体/碳复合材料后，反射率曲线明显向低频移动，增加了吸波频宽。

Cobalt ferromagnet/carbon and nickel cobalt copper ferromagnet/carbon nano composite were prepared. Infrared and ultraviolet-visible spectra were tested in range of 2.5-25 μm and 200-800 nm, while the extinction coefficients were calculated by using Lambert-Beer law. The extinction coefficients of cobalt ferromagnet/carbon composite, especially nickel cobalt copper ferromagnet/carbon composite increased after calcination. Nickel cobalt copper ferromagnet/carbon composite attained at 0.36 m²·g^-1 and exceeded 0.15 m²·g^-1 in the range of 3-16 μm. When the ratio of Nickel cobalt copper ferromagnet/carbon composite to acetylene black is 5:1, the extinction coefficient of the mixture reached 1.25 m²·g^-1 and exceeded 0.90 m²·g^-1 in the range of 3-5 μm and 8-14 μm. For ultraviolet-visible band, both cobalt ferromagnet/carbon composite and nickel cobalt copper ferromagnet/carbon composite exhibited show excellent extinction property. The different of main mechanism between infrared and ultraviolet-visible range were discussed. The reflectivity curves were test by adopting Arch Method in the range of 2-18 GHz. Mixing ferromagnet/carbon composite, the reflectivity curve of FeNi/carbon fiber moved to lower frequencies, as well as the absorbing bandwidth broadened.
