Abstract

A novel two-dimensional electromagnetic (EM) absorbers which consist of LaFeO3 nanoparticles embedded on hierarchical amorphous carbon nanosheets were fabricated by a simple one-pot method. By inducing A-site cation deficiency in LaFeO3 perovskite, the properties of EM absorption were optimized due to the polarization of dipoles between O vacancy and Fe4+. This research is expectant to provide a new strategy for the improved EM absorption performance by inducing the A-site cation deficiency in perovskite crystal lattices. By the magnetic ferrite nanoparticles doped in the dielectric carbon sheets, we got the best La0.8FeO3−y/C possessing larger absorption bandwidth 5.4 GHz from 12.6 to 18.0 GHz and minimum reflection loss of − 20.4 dB while La0.6FeO3−y/C which hit the minimum RL value − 25.0 dB at 14.8 GHz with the thickness of 3.75 mm.
