Abstract

The Ba_1-xCa_xFe_11.4Co_0.6O₁₉ (x = 0.0, 0.2, 0.4, 0.6, and 0.8) composites with wide-bandwidth and good absorption performance were prepared. The M_S of ceramics increases from about 62.4 to 83.4 emu g⁻¹ as x rises from 0 to 0.6, which demonstrates that the desirable magnetic properties of such ceramics is obtained by adjusting the content of Ca²⁺. A bandwidth of reflection loss (RL) below - 5 dB can be obtained for frequencies from 5.9 to 18 GHz with the Ba_0.4Ca_0.6Fe_11.4Co_0.6O₁₉ ceramic and a thickness of 2.0 mm, and a larger RL value of −34.1 dB is observed at 8.2 GHz for the Ba_0.6Ca_0.4Fe_11.4Co_0.6O₁₉ ceramic. These results suggest the developed ceramics could act as effective and wide-bandwidth microwave absorbing materials to meet commercial and military applications.
