Claim 13:
14. A method, comprising:
forming a printed circuit arranged as a base material stack having electrically conductive layer structures and at least one electrically insulating layer structure;
forming a magnetic stack as an alternating sequence of substantially planar magnetic layers and substantially planar dielectric bonding layers between each pair of adjacent magnetic layers, wherein the planar magnetic layers include a nanocrystalline magnetic material and each bonding layer is thermally stable at least up to 300° C., the magnetic stack having at least one bonding layer bonding two respective planar magnetic layers;
inserting the magnetic stack as an inlay for embedding into the printed circuit board; and
coupling a coil structure with the magnetic stack;
wherein a stacking direction of the magnetic layers and the at least one bonding layer is parallel to a direction of a winding axis of the coil structure.
