摘要: The intrinsically core/shell structured La0.6Sr0.4MnO3nanoparticles with amorphous shells and ferromagnetic cores have been prepared. magnetic, dielectric microwave absorption properties are investigated in the frequency range from 1 to 12 GHz. An optimal reflection loss of −41.1 dB is reached at 8.2 GHz a matching thickness 2.2 mm, bandwidth less than −10 obtained 5.5–11.3 for absorber thicknesses 1.5–2.5 mm. excellent consequence better electromagnetic due existence protective shells, cores, as well particular microstructure. As result, may become attractive candidates new types wave materials.
