Design of ternary-component X-band microwave absorber based on FeCo/Sr hexaferrite/PANI nanocomposite in silicon resin matrix

This work reports on the design and investigation of a new microwave absorber prepared from the combination of Sr-hexaferrite as a hard magnetic material, FeCo nanoparticles as a soft magnetic material, and polyaniline PANI as a dielectric-loss material. The prepared microwave absorber was characterized structurally and morphologically by X-ray diffractometry and scanning electron microscopy. The magnetic properties of the absorber were studied...
