“…Experimental results for real samples are usually influenced by dirt and protective capping layers, which have been shown to reduce the size of the observed effects [45,46]. It is thus very likely that our values for the Kerr angles are larger than they would be in the experiment [47,48]. In the visible range of the electromagnetic spectrum our results are well below 1…”

We investigate the anisotropy of the optical properties of thin Fe films on GaAs(001) from first-principles calculations. Both intrinsic and magnetization-induced anisotropy are covered by studying the system in the presence of spin-orbit coupling and external magnetic fields. We use the linearized augmented plane wave method, as implemented in the WIEN2K density functional theory code, to show that the C 2v symmetric anisotropy of the spin-orbit coupling fields at the Fe/GaAs(001) interface manifests itself in the corresponding anisotropy of the optical conductivity and the polar magneto-optical Kerr effect. While their magnetization-induced anisotropy is negligible, the intrinsic anisotropy of the optical properties is significant and reflects the underlying C 2v symmetry of the Fe/GaAs(001) interface. This suggests that the effects of anisotropic spin-orbit coupling fields in experimentally relevant Fe/GaAs(001) slabs can be studied by purely optical means.

“…In order to observe these phenomena, the surface roughness must be smaller than the electron wavelength at the Fermi level. This effect influences almost all the physical properties, for example inverse photoemission and photoemission [61,62], magnetic anisotropy [63], magneto-optic response [64][65][66], electrical conductivity [67], Hall effect [67], superconductivity [69], etc. Even at an early stage of growth, the film-growth is influenced by quantum well effect via its surface free energy [70,71].…”

This paper describes the magneto‐optical effects of metallic multilayers under the condition of total internal reflection. In the framework of the Green's dyadic technique, we present numerical simulations which account for the variation of the magneto‐optical signal with either the angle of incidence or the wavelength. Kerr and Faraday rotations are found to increase significantly around the critical angle. We also discuss the importance of plasmon effects in the structure of the Kerr and Faraday rotations spectra.
