The ferromagnetic semiconductor CdCr2S4 has been prepared in the form of hot-pressed polycrystalline samples having high optical transmission and Faraday rotation in the near-ir spectral region. In the region 900–1400 nm, the figure of merit exceeds 60° dB−1 at 4.2 °K and 30° dB−1 at 80 °K. It is thus an efficient and potentially useful magneto-optic material at liquid-nitrogen temperature.
