Abstract

Ein Magnetkern (1) aus einem Verbund aus plättchenförmigen Partikeln (5) mit der Dicke D und einem Bindemittel weist einen besonders linearen Verlauf der Permeabilitätszahl über einem vormagnetisierenden Gleichfeld auf. Dazu weisen die plättchenförmigen Partikel (5) eine amorphe Volumenmatrix (8) auf, in die an der Oberfläche (6, 7) des Partikels (5) Bereiche (9) mit einem kristallinen Gefüge eingebettet sind, die eine Dicke d mit 0,04 * D ≤ d ≤ 0,25 * D aufweisen und einen Anteil x mit x ≥ 0,1 der Oberfläche (6, 7) des Partikels (5) bedecken.
