Ultrasensitive magnetic sensor with magneto-optically active material with high verdet constant KU Leuven
A high-resolution sensor of magnetic field sensor system and materials for use in such a system are described. The sensor systems measure a magnetic field using inorganic and/or organic magneto-optically active materials, e.g. polymer material and have an interferometer based on Faraday rotation. The polymer material is preferably in the form of a film. The polymer material has an optical property that is sensitive to the magnetic field, e g the Faraday rotation effect. The present invention also provides a sensor head structure comprising the above polymer material. The sensor head may be ...
