A ferromagnetic-polymer composite material comprises a polymer and a plurality of ferromagnetic film platelets disposed in the polymer. Each ferromagnetic film platelet comprises first and second insulator layers and a ferromagnetic layer disposed between the first and second insulator layers. The ferromagnetic layer can be magnetically anisotropic in which a hard axis of magnetization is aligned parallel to a plane that passes through and parallel to an interface between the first insulator layer and the ferromagnetic layer. The easy and/or hard axes of magnetization in the ferromagnetic film platelets can be aligned. An inductor can have a core formed of the ferromagnetic-polymer composite material.

A laminating structure includes a first magnetic layer, a second magnetic layer, a first spacer disposed between the first and second magnetic layers and a second spacer disposed on the second magnetic layer.
