N2 - Enhanced microwave absorption Ba0.4−xLaxCa0.6Fe11.4Co0.6O19 (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 Ba0.4Ca0.6Fe11.4Co0.6O19 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 Ba0.1La0.3Ca0.6Fe11.4Co0.6O19 ceramic developed with an effective, a thin, and wide-bandwidth absorption is highly promising materials for electromagnetic application.
