Abstract

L'invention concerne les appareils destinés à mesurer les champs magnétiques et qui sont aussi connus sous le nom de magnétomètres. Elle consiste à mesurer par une méthode de zéro l'influence de l'effet Faraday du champ à mesurer sur un faisceau d'énergie rayonnée se propageant de manière guidée dans une couche mince de matériau magnétique. Elle permet de construire des magnétomètres sensibles et robustes.
