We tabulate the wavelength dependence of the complex magneto-optic constants for epitaxial fcc (001) and hcp (11-bar00) Co films with the magnetization along two different in-plane crystallographic directions. The magneto-optic constants of epitaxial hcp Co films are strongly dependent on crystallographic direction for the same sample, while those of epitaxial fcc Co films are not, as anticipated from the trends in the magnetic anisotropy due to the spin-orbit interaction. Our results for (i) the anisotropic magneto-optic constants, (ii) the magnetic anisotropy, and (iii) the indices of refraction, are compared to other studies of Co.
