摘要:
An integrated magnetic inductor is provided with an inductor coil, magnetic film, and a substrate. The magnetic film can be placed between the neighboring inductor coils, and the thickness of the magnetic film is greater than the coil thickness. In addition, the magnetic film includes exchange-coupled magnetic materials. The exchange-coupled magnetic materials provide improved permeability and fFMR at the frequency of interest for the integrated magnetic inductor.
