This paper presents measurement of the Bi₁₂GeO₂₀ optical activity temperature dependence. The measurement was performed by orthogonal polarization detection and the temperature was measured using a thermographic camera. Since Bi₁₂GeO₂₀ crystals exhibit both the Faraday rotation and the optical activity, the analysis of electromagnetic wave propagation through such crystals is presented. Compensation of the temperature dependence for current and magnetic field sensors based on Faraday rotation is proposed.
