Influence of Magnetic Losses on Microwave Absorption by Carbon-Nanotube Nanocomposites with a Low Concentration of Ferromagnetic Nanoparticles

The absorption properties of magnetic nanocomposites based on carbon nanotubes with a low concentration of ferromagnetic nanoparticles have been investigated in the 78–118 GHz frequency range. A correlation was established between the absorption properties of the nanocomposites and the character of the magnetostatic interaction between nanoparticles.
