Title (EN) MAGNETIC ISOLATOR, METHOD OF MAKING THE SAME, AND DEVICE CONTAINING THE SAME
(FR) ISOLANT MAGNÉTIQUE, SON PROCÉDÉ DE FABRICATION ET DISPOSITIF LE CONTENANT
Abstract:
(EN) A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by gaps. At least some of the electrically-conductive soft magnetic islands have an outer insulating oxidized layer that electrically insulates them from adjacent electrically-conductive soft magnetic islands. The gaps at least partially suppress electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.
(FR) Isolant magnétique comprenant un film diélectrique ayant une couche de matériau magnétique tendre électroconducteur liée à celui-ci. La couche de matériau magnétique tendre électroconducteur comprend des îlots magnétiques tendres électroconducteurs sensiblement coplanaires séparés les uns des autres par des espaces. Au moins certains des îlots magnétiques tendres électroconducteurs ont une couche oxydée isolante extérieure qui les isole électriquement des îlots magnétiques tendres électroconducteurs adjacents. Les espaces suppriment au moins partiellement le courant de Foucault électrique induit dans la couche de matériau magnétique tendre en présence d'un champ magnétique externe appliqué. L'invention concerne également un dispositif électronique comprenant l'isolant magnétique et un procédé de fabrication de l'isolant magnétique.
