Abstract
The present disclosure relates to a magnetic multilayer composite that may include a core substrate layer, an outer magnetic layer overlying a first surface of the core substrate layer, and an inner magnetic layer underlying a second surface of the core substrate layer. The composite may include a magnetic volume ratio V/Vof at least about 0.005, where Vis equal to the total volume of magnetic material in the composite and Vis the total volume of substrate. The composite may further include a permeability rating (X, Y), where the permeability rating (X, Y) is equal to a peak point (X, Y) along a plot of the imaginary part of magnetic permeability (μ″) of the composite plotted as a function of frequency, where X is within the range of 10 MHz to 10 GHz, and Y is greater than 100.
