Figure 5

Frequency dependence of real permeability (μ′) for Ag/SiO2 composites (a), the schematic diagram of magnetic response due to the induced current loops in Ag/SiO2 composites (b), and frequency dependence of μ/(f) for Ag/SO2 composites with different silver content (c, d). The red solid lines in (a) are the calculation results by the relation of with high reliability.
