Aufbau eines magnetooptischen Rasternahfeldmikroskops im Reflexionsmodus und Test an periodischen Mikrostrukturen und magnetooptischen Speichermedien
… SNOM, which can measure the Faraday and Kerr rotation of transparent respective opaque samples quantitatively with high spatial resolution, was built. After an introduction into the principles of near-field optics and magneto-optics the experimental set-up of a SNOM is outlined with …

Effects of asymmetry on electron spin dynamics in gallium arsenide quantum wells
… temporal spin dynamics, the time-resolved Kerr rotation technique was adapted in order to compensate for reduced rotational symmetry in the (110) crystallographic direction. An investigation into the effect of a transverse electric field on electron spin lifetimes was conducted. By …

Spin-coherence and -dephasing of donor and free conduction band electrons across the metal-insulator transition in Si:GaAs
… basic experimental setups, like time-resolved Kerr/Faraday rotation spectroscopy, as well as their applicationto the model system Si:GaAs. Systematics studies of the transverse spin lifetime depending on various external parameters, such as temperature, magnetic field, laser excitation power …

Investigation of spin-caloric and spin-orbit torque materials by vectorial spin Seebeck measurements and an advanced x-ray magnetic reflectivity analysis
… band structure and a considerable magneto-optic Kerr effect (MOKE). In addition, strong intrinsic spin-orbit torque effects have been observed in this system. When these are combined with the half-metallic band structure of PtMnSb, a pronounced spin polarization can be generated which is very …

Exploring linear and nonlinear electromagnetic responses in topological materials
… states. We then apply our results to study the Kerr effect in the moiré Chern insulator, which exemplifies the experimental pertinence of spatially inhomogeneous fields in such systems, given their large effective lattice constants. We further examine the nonlinear, magnetic, and magnetoelectric …
