Er-doped barium ferrites,BaEr0.3Fe11.7O19,was synthesized through a sol-gel method. PANI/BaEr0.3Fe11.7O19 composite was prepared through an in-situ polymerization with as-synthesized ferrite and aniline as raw materials. The structure,morphology and electromagnetic property of composite were characterized by X-ray diffraction,scanning electron microscopy and vector network analyzer. The results showed that the composite material was spherical with particle size less than 100 nm. When matching thickness was 3mm,the absorption peak position and the reflectivity of PANI/BaEr0.3Fe11.7O19 were 12 GHz and-42 dB,respectively. The bandwidth of-10 dB was 10-15.5 GHz,and bandwidth was 5.5 GHz.
