Ferromagnetism of novel ultrathin films and multilayers: A study of Ru/C(0001) and Fe/Mn/Fe/Pd(100) using magneto-optic Kerr effect and spin-sensitive electron spectroscopies
… depth profiling. We use SIMPA and the surface magneto-optic Kerr effect to study exchange coupling in Fe/Mn/Fe/Pd(100) multilayers. The intervening Mn layer is grown in a wedge shape ranging in thickness from 0 to 9 monolayers. Our results show that both Fe layers are coupled ferromagnetically …

Micromagnetic modelling and magneto-optical characterization of Ni/V2O3 hybrid structures
… sapphire, Al2O3, were investigated using MOKE (magneto-optic Kerr effect). Three samples show a fourfold symmetry in coercivity with very small but similar change in magnetic remanence. For comparison micromagnetic simulations were done in Mumax3. The samples have a well defined growth …

Study of the Valence Tautomer Complex [Co(sq)(cat)(3-tpp)2] for Applications in Molecular Spintronics
… a custom made, fully automated Vibrating Sample Magnetometer (VSM) with a sensitivity on the order of 1 × 10-5 emu, as well as a fully automated, variable temperature, under vacuum electron transport stage, and a magneto-optic Kerr effect apparatus (MOKE). Additional experimental methods used to …

Spin transport in few-layer graphene
… regarding the interpretation of local magnetoresistance (MR), where the spin-valve signal can be confused with tunnelling anisotropic magnetoresistance (TAMR) at the contacts. The magnetisation-reversal in unpatterned films of La0.67Sr0.33MnO3 (LSMO) on substrates of NdGaO3 (001), …

Non-ideal exchange springs in DyFe2/YFe2 superlattices
… latter has been studied experimentally using the magneto-optic Kerr effect (MOKE), at room temperature. This work was also complimented by 1D computer simulations, involving numerical solution of the Landau-Lifshitz-Gilbert equations. In contrast to the well accepted low-temperature behaviour, …

Low temperature Kerr effect study of magnetic topological insulators and other magnetic structures
… systems is presented, with an emphasis on the magneto-optic Kerr effect (MOKE) characterisation. The design and construction of a MOKE microscope is described, for simultaneous magneto-optical and magneto-transport measurements in an applied field of up to 9 T at temperatures from 1.5 to 300 K. …

Magnetic and thermal properties of metallic antiferromagnetic materials
… of the lack of net magnetization. The linear magneto-optic Kerr effect (MOKE) is often used to probe magnetism of ferromagnetic materials, but MOKE cannot be applied to collinear antiferromagnets due to the cancellation of sublattice magnetization. Magneto-optic constants that are quadratic in …

Optical studies of current-induced spin-orbit effects in magnetic systems
… phenomena, including the spin Hall effect, Rashba-Edelstein effect and the resultant spin-orbit torques (SOTs), have fueled the development of spintronics for more than a decade thanks to their promising magnetization-switching efficiencies. This dissertation presents experimental …

Investigation of spin-caloric and spin-orbit torque materials by vectorial spin Seebeck measurements and an advanced x-ray magnetic reflectivity analysis
… Most fundamentally, the inverse spin galvanic effect (ISGE) can directly generate a non-equilibrium spin polarization which subsequently induces a spin-orbit torque (SOT) on the magnetization. Phenomena like the ISGE take advantage of the relativistic momentum transfer between electron and spin …
