Corrosion-resistive magnetic powder Fe@SiO2 for microwave applications

Iron powder particles were coated with a thin SiO2 shell for protection of corrosion. Dynamic magnetic behavior of the as-synthesized material was studied in comparison with uncoated metal in terms of frequency dispersion of the microwave permeability and permittivity. A uniform 100-nm SiO2 shell pr...
