FOROXID: Magneto-Optical Sensorics

This project aims to examine or develop magneto-optical sensors for analyzing the distribution of magnetic fields or electric power and to integrate them into a light microscope. The magneto-optic sensors are based on iron-garnet layers which are to be applied to suitable substrates by means of laser ablation. To ensure a high degree of sensibility it is important to obtain layers as thick as possible, which can only be realised by a multi-layer structure. In this connection we will study the origin, the type and dynamics of defects and phases of the films and their influence on magneto-optical properties. Based on the findings, a demonstrator device will be designed. For this purpose, the layers are additionally provided with high-quality mirror layers and protective layers.
