Title (EN) MAGNETIC MULTILAYER SHEET
(FR) FEUILLE MAGNÉTIQUE MULTICOUCHE
Abstract:
(EN) A multilayer magnetic sheet is described which comprises a plurality of stacked magnetic component layers separated by first electrically insulating layers. Each of the plurality of magnetic component layers comprises a plurality of isolated magnetic sublayers having a magnetic layer thickness of less than one micron. The multilayer magnetic sheet has a magnetic fraction between about 5% and about 80%; a total magnetic thickness of greater than or equal to 5 microns; and a relative composite permeability of greater than about 20.
(FR) L'invention concerne une feuille magnétique multicouche comprenant une pluralité de couches de composants magnétiques empilées et séparées par de premières couches électriquement isolantes. Chacune de la pluralité de couches de composants magnétiques comprend une pluralité de sous-couches magnétiques isolées présentant une épaisseur de couche magnétique inférieure à un micron. La feuille magnétique multicouche présente une fraction magnétique comprise entre environ 5% et environ 80%; une épaisseur magnétique totale supérieure ou égale à un micron; et une perméabilité de composite relative supérieure à environ 20.
