Abstract

This paper reports on the magneto-optical properties of an electron beam evaporated EuS thin-film characterized at room temperature. The refractive index of EuS was measured using ellipsometry in the visible part of the spectrum. The dispersion curve of the Verdet constant was measured in the wavelength range between 600 and 800 nm. We fitted an analytical expression for the dispersion curve in the range of 663-785 nm. In addition, we find that the Verdet constant of thin-film EuS is one order of magnitude higher than the commonly used terbium gallium garnet crystal.
