The complex dielectric constant of Cd0.8Mn0.2Te single crystals is determined from reflection measurements in the photon energy range from 1.75 to 2 eV at the lattice temperature T = 2 K. The light reflection model includes exciton absorption and dispersive background dielectric constant contribution. The same model is found to be efficient in describing the band of nonreciprocal reflection arising in nonzero magnetic field in the Voigt geometry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
