MEASURING HEAD FOR MAGNETOMETER AND MAGNETOMETER INCORPORATING SUCH A HEAD

摘要

The invention relates to magnetometers making it possible to measure a magnetic field by the Faraday effect in a thin YIG layer, It involves taking a YIG layer which is sufficiently thick to permit a multimode transmission of the polarized light beam, as well as the entrance and exit of said beam by the edge of the layer. It makes it possible to produce a magnetometer head, whose elements are integrated on a substrate and whose volume is approximately 1 cm3.
