Electromagnetic sensors#

Multi-dimensional magnetic sensors based on the GMR and TMR effect, respectively, while using ferromagnetic thin films, are in the focus of this topic. However, they can be applied both in the direct measurements of magnetic fields and in the measurement of distance, position and rotation. Furthermore, sensors for near field measurements of electromagnetic fields and determination of radiation characteristics were developed.
