Kurzbeschreibung (Abstract)
Metal-filled carbon nanocomposites containing 20 wt% of metallic FeCo nanoparticles were synthesized by means of infrared heating of precursors (polyacrylonitrile – iron acetylacetonate - cobalt acetate). This fabrication approach shows promise for making radiation-absorbent materials in short one-step process with ability to control the size of nanoparticles and attune the composition of the metallic components. In this work the magnetic behavior of reaction products obtained at different stages of the synthesis have been investigated in detail. We report on the influence of the annealing temperature on evolution of the structure, chemical composition, size, surface morphology, spontaneous magnetization and coercivity of the FeCo nanoparticles.
