摘要

Nanocomposites composed of magnetic and dielectric materials are suitable for high performance electromagnetic wave absorbers due to their great impedance matching. In this work, the microwave absorbing properties of Fe ₃ O ₄ –BaTiO ₃ composites were investigated over a frequency range of 1–18 GHz Fe ₃ O ₄ –BaTiO ₃ composites present significantly enhanced microwave absorption performance compared with BaTiO ₃ . For the optimal Fe ₃ O ₄ (x)–BaTiO ₃ (1-x) (x = 0.8) composite, the reflection loss (RL) could reach −47.4 dB at 12.26 GHz with a matching thickness of 2.2 mm, the bandwidth below −10 dB is 5.0 GHz, which is six times higher than BaTiO ₃ . The broadened absorption bandwidth is resulted from better impedance matching. This results show that Fe ₃ O ₄ –BaTiO ₃ composites can be used as an excellent microwave absorption materials with strong absorption and broad bandwidth.
