Ultrathin films on semiconductor substrates : growth, magneto-optical characteristics and spin injection
… especially their magneto-optical properties and spin injection.Magnetic ultrathin films were grown on different GaAs substrates using an e-beamevaporation technique. The MBE system which is used to fabricate and analyseultrathin films is home designed and assembled. …

TIME-DOMAIN INVESTIGATION OF ACOUSTICALLY AND THERMALLY DRIVEN MAGNONS
… magnetization dynamics of the Ni thin films via magnetoelastic coupling. In a second experiment, the TG approach has been exploited to drive coherent magnons at a selected wavevector non-relying on the magnetoelastic coupling but rather on the spatially modulated temperature profile generated by …

Magnetisierungsumkehr und -dynamik in Exchange-Bias-Systemen
The present thesis describes magneto-optical analyses of exchange bias thin film systems. Exchange bias (EB) is a unidirectional anisotropy originating from coupling of a ferromagnetic with an antiferromagnetic layer. The magneto-optical Kerr effect (MOKE) allows for detection of the longitudinal …

An Investigation of the Structure, Pinning and Magnetoresistance of Domain Walls in Ni81Fe19 Planar Nanowires
… microstructural influences on the magnetic and magnetoresistance properties, along with a thorough understanding of the effect of geometrical confinement on domain wall (DW) structure and pinning behaviour in nanowire structures. The out-of-plane structural properties of thermally evaporated …

Ultrafast magnetization dynamics of lanthanide metals and alloys
… x-ray magnetic circular dichroism (XMCD), the magneto-optical Kerr effect (MOKE) and magnetic second harmonic generation (MSHG). The magnetization dynamics is analyzed from the time scale of a few fs up to several hundred picoseconds (ps). The contributions of electrons, phonons, spin …

Designer magnetoplasmonics for adaptive nano-optics
… enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to …
