Abstract
The absorption Coefficient and the interband Faraday rotation of EuS, EuSe, and EuTe thin films have been measured as a function of the photon energy (1-6 eV), the temperature (2.7-300 K), and the applied magnetic field (0.1-11.5 kOe). From the Faraday rotation (FR) we compute the circular magnetic dichroism and from both and the optical constantsnandkwe derive the imaginary part of the off-diagonal elements of the complex conductivity tensor Im &xy. Integral values of the latter depend on the spin polarization of electronic states and permit a distinction between pd and fd transitions.Keywords
