Abstract: We fabricated a core inductor with an aluminum nano-polycrystalline structure, which is a ferromagnetic body, for the first time. A fabricated Al nano-polycrystalline structure was found to work as an inductor core. Bulk Al, which is considered a non-magnetic body, was not attracted to magnets. However, our previous research demonstrated that Al nano-polycrystalline structures are ferromagnetic.
