Abstract: Stacked magnetic cores that can achieve high density with a small footprint are provided. A stacked magnetic core can include a plurality of magnetic films with an adhesive film between each magnetic film and the adjacent magnetic film(s). That is, the magnetic films and adhesive films can be disposed in an alternating fashion. Each adhesive film can be a dielectric/insulating film such that each magnetic film is electrically insulated from every other magnetic film.

Abstract: Stacked magnetic cores that can achieve high density with a small footprint, as well as methods of fabricating and using the same, are provided. A stacked magnetic core can be fabricated by depositing nanomagnetic films with control in composition and nanostructure via a continuous electroplating process. The magnetic films are interspersed with thin adhesive films (that can be insulating) in an automated roll-to-roll process. That is, the magnetic films and adhesive films are disposed in an alternating fashion. The adhesive films can keep the magnetic films completely electrically isolated from each other, while also adhering adjacent magnetic films to each other.
