Abstract

Abstract Translated from French L'invention concerne les magnétomètres qui permettent de mesurer un champ magnétique par effet Faraday dans une couche mince de YIG (113). Elle consiste à prendre une couche de YIG (113) suffisamment épaisse pour permettre une transmission multimode du faisceau de lumière polarisé ainsi que l'entrée et la sortie de ce faisceau par la tranche de la couche. Elle permet de réaliser une tête de magnétomètre dont les éléments sont intégrés sur un substrat (102) et dont le volume est de l'ordre du centimètre cube. The invention relates to magnetometers which make it possible to measure a magnetic field by the Faraday effect in a thin layer of YIG (113). It consists in taking a layer of YIG (113) sufficiently thick to allow a multimode transmission of the polarized light beam as well as the entry and the exit of this beam by the edge of the layer. It makes it possible to produce a magnetometer head whose elements are integrated on a substrate (102) and whose volume is of the order of a cubic centimeter.
