摘要：
A ferromagnetic-polymer composite material (40) comprises a polymer (110) and a plurality of ferromagnetic film platelets (300) disposed in the polymer (110). Each ferromagnetic film platelet (300) comprises first and second insulator layers (331, 332) and a ferromagnetic layer (320) disposed between the first and second insulator layers (331, 332). The ferromagnetic layer (320) can be magnetically anisotropic in which a hard axis of magnetization (324) is aligned parallel to a plane that passes through and parallel to an interface between the first insulator layer (331) and the ferromagnetic layer (320). The easy and/or hard axes of magnetization (322, 324) in the ferromagnetic film platelets (320) can be aligned. An inductor can have a core formed of the ferromagnetic-polymer composite material.
