Short summary
This article discusses the properties of different diamagnetic and paramagnetic materials for a basic current/magnetic field sensor system set up with different relative orientations of analyzers and polarizers. The paper analyzes a linearity range of different materials and their sensitivity for different wavelengths. Terbium doped glass, terbium gallium garnet, doped TGG and dense flint glass materials are used for analysis based on the Faraday rotation principle.
