Abstract

Enhanced microwave absorption Ba_0.4−xLa_xCa_0.6Fe_11.4Co_0.6O₁₉ (BLCFCO, x = 0.0, 0.1, 0.2, 0.3, and 0.4) ceramics were prepared. The characteristics of the BLCFCO ceramics such as phase, microstructure, magnetic properties, electromagnetic properties, and reflection loss (RL) were investigated. The lanthanum-based substitution enhances the microwave absorption properties of the Ba_0.4Ca_0.6Fe_11.4Co_0.6O₁₉ ceramics, and the RL values less than − 5 dB are obtained in 8.6–12.9 GHz with a thickness of 1.5 mm. A maximum RL with − 28.3 dB can be obtained at 10.6 GHz for the composites with x = 0.3. These results indicate that the Ba_0.1La_0.3Ca_0.6Fe_11.4Co_0.6O₁₉ ceramic developed with an effective, a thin, and wide-bandwidth absorption is highly promising materials for electromagnetic application.
