Abstract
Methods of manufacturing are disclosed for an inductor that includes a magnetic core lying in a core plane. The magnetic core includes a vertical laminated structure with respect to the core plane of alternating ferromagnetic vertical layers and insulator vertical layers. An easy axis of magnetization can be permanently or semi-permanently fixed in the ferromagnetic vertical layers along a first axis orthogonal to the core plane. A hard axis of magnetization can be permanently or semi-permanently induced in the ferromagnetic vertical layers, the hard axis of magnetization lying in a plane that is orthogonal to the first axis.
