Abstract. Based on the experimental data obtained, we performed the theoretical investigation of the external reflectance coefficients of uniaxial optically anisotropic polar ZnO single crystals subjected to the action of a high uniform magnetic field that is parallel to the crystal axis С and the surface under the condition that E B ⊥ r r (the Voigt configuration, Fig. 1). For the first time, we have found the regions in the external reflection spectra of ZnO single crystals, where new oscillations appear which are due to the effect of a high uniform magnetic field. A possibility of solving the direct and inverse problems in such a case is demonstrated.

Keywords: Voigt configuration, ZnO, reflection spectra.
