A nanomagnetic inductor core (1) comprises nanowires (3), segmented in the axial direction, formed in pores of a porous, electrically-insulating template. The nanowires include segments (4a,4b) made of high-permeability material and, interposed between adjacent segments (4a,4b) in the axial direction of the nanowire, there are segments of dielectric material (5). Each segment (3a) of high- permeability material has a length (SL), in the axial direction of the nanowire, no greater than the size of a single magnetic domain. Inductors (40) and LC interposers using such nanomagnetic inductor cores (1) are described, as well as associated fabrication methods. |
