Ferroelectric-ferromagnetic composite materials |
摘要 |
A material which possesses both capacitive and inductive properties for suppressing electromagnetic interference is provided, wherein the material is a composite of a ferroelectric material and a ferromagnetic material. The ferroelectric-ferromagnetic composite material is formulated and processed so as to retain the distinct electrical properties of the individual constituents according to the relative quantities of the constituents present in the ferroelectric-ferromagnetic composite material. As a unitary composite element, the ferroelectric-ferromagnetic composite is readily formable to provide a compact electrical filter whose filtering capability is highly suitable for suppressing electromagnetic interference from sources internal and external to an automotive environment. The sintered composite has a very low porosity; interconnectivity between the ferroelectric and ferromagnetic phases; and has no chemical reaction between the ferroelectric and ferromagnetic phases to produce a third phase.
