| titleOfInvention | Ultra-sensitive magnetic sensor using giant Faraday rotation |
| abstract | The present invention relates to a high-precision magnetic field sensor system and materials used in the system. The sensor system includes an interferometer that measures a magnetic field using an inorganic and / or organic magneto-optically active material such as a polymer material and uses Faraday rotation. The polymer material is preferably in the form of a film. The polymer material has optical properties such as a Faraday rotation effect that is sensitive to a magnetic field. The present invention also provides a sensor head structure comprising the above polymer material. The sensor head may include an optical fiber or a mirror. In particular, the present invention provides a fiber Sagnac interferometer for measuring the rotation of the plane of polarization of light. The present invention provides a Sagnac interferometer using fibers or mirrors that can be applied with a passive phase bias to detect a magnetic field. The present invention has the following three main embodiments. 1. Sensing material: a polymer comprising a conjugated polymer such as polythiophene and / or superparamagnetic nanoparticles exhibiting giant Faraday rotation. 2. A magnetic field probe comprising the polymer or a composite material of the polymer and nanoparticles (for example, a film). 3. Sensor: A sensor in which a Sagnac interferometer using an optical fiber is combined with the magnetic field probe. |
