Abstract
A nanomagnetic inductor core that includes: a porous, electrically-insulating template having high-permeability material in the pores thereof to constitute elongated nanowires, and wherein the elongated nanowires are segmented along their axial direction; and a segment of dielectric material interposed between adjacent segments of the high-permeability material along the axial direction of the nanowire; wherein each segment of the high-permeability material has a length, in the axial direction of the nanowire, no greater than a size of a single magnetic domain, and wherein a maximal cross-sectional dimension of the nanowire is no greater than the size of the single magnetic domain. Inductors and LC interposers using such nanomagnetic inductor cores, as well as associated fabrication methods.
