    Abstract: A ferromagnetic-polymer composite material comprises a polymer and a plurality of ferromagnetic film platelets disposed in the polymer. Each ferromagnetic film platelet comprises first and second insulator layers and a ferromagnetic layer disposed between the first and second insulator layers. The ferromagnetic layer can be magnetically anisotropic in which a hard axis of magnetization is aligned parallel to a plane that passes through and parallel to an interface between the first insulator layer and the ferromagnetic layer. The easy and/or hard axes of magnetization in the ferromagnetic film platelets can be aligned. An inductor can have a core formed of the ferromagnetic-polymer composite material.

    Abstract: A method for manufacturing a vertically-laminated ferromagnetic core includes (a) depositing a conductive seed layer on or over a first side of a substrate; (b) depositing a masking layer on or over a second side of the substrate, the first and second sides on opposite sides of the substrate; (c) forming a pattern in the masking layer; (d) dry etching the substrate, based on the pattern in the masking layer, from the second side to the first side to expose portions of the conductive seed layer; and (e) depositing a ferromagnetic material onto the exposed portions of the conductive seed layer to form vertically-oriented ferromagnetic layers.
