中文摘要：

采用NaBH4溶液还原FeCl3的方法制备Fe-B颗粒，并在Ar／O2气氛下干燥，使其表面不完全氧化，得到了Fe—B／Fe3O4纳米复合粒子。该粒子具有清晰的核壳结构，内核Fe-B尺寸约为20－50nm，外壳Fe3O4厚度约为3nm。将样品与石蜡按质量比1：1制成同轴样品，测试其2～18GHz下的电磁参数并进行分析计算，研究发现，由于偶极子极化、自然共振和涡流损耗，该纳米复合粒子粉末具有优良的吸波性能，其反射损耗RL在频率为12．0GHz的时候达到最小值－31dB，RL值低于－20dB（即吸收率高于99％）的频率范围为10．1～14．2GHz。

英文摘要：

Fe-B/Fe3O4 nanoparticles were prepared by chemical reduction with borohydride and dried in Ar/O2 atmosphere. The nanoparticles have clear core/shell structure with the Fe-B core of 20--50 nm and the Fe3 04 shell of 3 nm. The nanoparticles were mixed with paraffin （1 ： 1 in mass ratio） to form a ring sample for measuring the complex electromagnetic parameters in the frequency range of 2--18 GHz. It is found that the composite exhibits excellent microwave absorption properties （reflection loss 〈--20 dB ） in the range 10.1--14.2 GHz due to the orientational polarization, natural resonance and eddy current loss.
