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 Fe3O4-BaTiO3 composites were investigated over a frequency range of 1-18 GHz Fe3O4-BaTiO3 composites present significantly enhanced microwave absorption performance compared with BaTiO3. For the optimal Fe3O4(x)-BaTiO3(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 BaTiO3. The broadened absorption bandwidth is resulted from better impedance matching. This results show that Fe3O4-BaTiO3 composites can be used as an excellent microwave absorption materials with strong absorption and broad bandwidth.
