“…The MOKE signal increases drastically near the plasma frequency for each material in general, suggesting energy-independent and relatively small values at energies outside the plasma frequency. For example, Al has a plasma frequency of 15 eV [44], which is out of range compared to the MOKE spectra in the present study, which would also be noticeable for Ta.…”

Boron-induced electronic states of antiperovskite nitrides such as ferrimagnetic Mn4N were investigated via a combination of polar magneto-optical Kerr effect (p-MOKE) spectroscopy and spectroscopic ellipsometry (SE). The boron content in the Mn4N film varied from 0 to 4.3 at.%, for which the crystal structure was maintained. The amplitude of p-MOKE spectra and the diagonal and off-diagonal dielectric tensors decreased with increasing boron content, which is in agreement with magnetic properties such as magnetic anisotropy and saturation magnetization. These results were related to the lattice expansion and displacement of the charge density in Mn4N by boron doping. However, the peak energy of Lorentz oscillator in the diagonal elements of dielectric tensors suggests that a dominant inter-band transition was independent of boron content.

“…Knowledge of the permittivity tensor is crucial, since it allows theoretical prediction of complex physical properties of complicated multilayered nanostructures containing GdFe layers without necessity to manufacture multiple samples. This is especially useful for the design of advanced devices as holographic 3D displays based on structures consisting of more than 10 nanolayers [ 2 , 11 ].…”

Optical and Magneto-Optical Properties of Gd22Fe78 Thin Films in the Photon Energy Range From 1.5 to 5.5 eV

Optical and magneto-optical properties of amorphous Gd22Fe78 (GdFe) thin films prepared by direct current (DC) sputtering on thermally oxidized substrates were characterized by the combination of spectroscopic ellipsometry and magneto-optical spectroscopy in the photon energy range from 1.5 to 5.5 eV. Thin SiNx and Ru coatings were used to prevent the GdFe surface oxidation and contamination. Using advanced theoretical models spectral dependence of the complete permittivity tensor and spectral dependence of the absorption coefficient were deduced from experimental data. No significant changes in the optical properties upon different coatings were observed, indicating reliability of used analysis.

“…A magneto-optical spatial light modulator (MO-SLM) with a narrow pixel pitch has been proposed for realizing holographic movies [1][2][3] with a wide-viewing angle. [4][5][6][7][8][9][10][11][12][13] The pixel pitch of the SLM determines the viewing angle of the reproduced holographic image. For example, to obtain a viewing angle of 30°or more at a wavelength of 532 nm, a pixel pitch of 1 μm or less is required.…”

A submicron-scale magneto-optical light modulation device driven by current-induced domain wall motion (CIDWM) was fabricated for an electroholographic display application. The device consists of a Gd-Fe nanowire for light modulation and two Co/Pd hard magnets (HMs) with different coercivities. We succeeded in fabricating two HMs with different coercivities from a Co/Pd film by simply changing their length and realizing an antiparallel magnetization direction configuration for the HMs, which is very important for initial domain nucleation and the CIDWM. We confirmed successful domain wall motion and light modulation when a pulse current of ±0.8 mA was injected into the device, whose size was as small as 0.5 × 2 μm 2 . The current value was lower than that required for the previously reported light modulation device driven by spin-transfer switching.
