LOW-RETENTIVITY FOIL AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a foil (20) with low-retentivity characteristics (coercive field strength especially below 20 A/m, saturation inductance especially over 0.4 T). The inventive foil is provided with a magnetically anisotropic composite structure (V) consisting of anisotropic particles of an amorphous and/or nanocrystalline, ferromagnetic metal powder (21) and a plastic material (22). The metal powder (21) and the plastic material (22) that is present in the powdery or liquid form thereof are mixed, heated and converted into the foil form in order to produce said foil. The metal powder can be incorporated into or mounted to a carrier foil of the plastic material.
