Effect of the nanocrystalline state and electrical resistance of Fe and Fe75Si25 powders produced by the method of high-energy ball milling on the frequency dispersion of microwave material parameters

详细

The influence of the nanocrystalline state of Fe and Fe₇₅Si₂₅ particles and their electrical resistance on the microwave properties of composite materials that contain these particles has been investigated experimentally. The main factors that determine changes in the frequency dispersion of the permeability are the skin effect and the decrease in the internal field of anisotropy of the particles. In the case of Fe particles, the role of skin effect of prevails.
