“…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.

“…Spinel ferrite nanoparticles with superparamagnetic behavior have attracted much attention in nanoscience and nanotechnology because of their potential applications for magnetic resonance imaging, drug targeting, catalysis and highdensity magnetic recording devices [1][2][3][4][5][6]. Each type of application requires magnetic nanoparticles with specific physicochemical and magnetic properties that can be engineered during the synthesis process [7,8].…”

Magnetic Cr 3+x Fe 3+ 2 − x Fe 2+ O 4 (0 ⩽ x ⩽ 0.1) porous nanoparticles were prepared by the aqueous coprecipitation method. The resulting magnetic nanoparticles were characterized by using an x-ray diffraction (XRD), field enhanced scanning electron microscope (FESEM), transmission electron microscope (TEM), and vibrating sampling magnetometer (VSM). The nitrogen gas adsorption/ desorption isotherm showed a microporous structure of the obtained magnetic materials. A rod and round shape of Fe 3 O 4 was observed as using polyvinylpyrrolidone (PVP) and cetyltrimethylammonium bromide (CTAB) surfactant, respectively. The Fe 3 O 4 nanoparticles exhibited superparamagnetic properties with easy separation and re-dispersion in solution by using an external magnet. More remarkably, the saturation magnetization (M s ) was enhanced up to 1.2 times for doping Cr 3+ into the Fe 3 O 4 lattice. The effect of surfactants and Cr 3+ doping concentrations on size and the magnetic properties of Fe 3 O 4 nanoparticles are studied.
