Aufbau eines polaren Kerr Mikroskops zur Untersuchung von strominduzierter Domänenwandbewegung

We plan to convert an existing polarization conserving microscope into a polar Kerr microscope for the investigation of current induced domain wall motion. The thesis will comprise of the development of the experimental set-up, the development of measurement software and first test experiments.

Spinpumpen in Heterostrukturen bestehend aus magnetischen Weyl-Halbmetallen und Schwermetallen

Magnetic Weyl semi-metals combine magnetic order and a topological electronic band structure. It is expected that mutual spin-to-charge conversion is particularly efficient in these materials. We will study mutual spin-to-charge conversion using methods of ferromagnetic resonance.

Spinwellenausbreitung in Spin Hall Nano-Oszillatoren

Nanoconstrictions in ferromagnet/heavy metal bi-layers can be used to generate auto-oscillations of the dynamic magnetization via the dc spin Hall effect. We use time resolved magneto-optic Kerr microscopy with 250 nm spatial and sub-picosecond temporal resolution to study the excitation of localized auto-oscillations. Here, we would like to study coupling of localized dynamic modes to propagating modes in the ferromagnetic leads.
