Interplay between optical and magneto-transport phenomena in strongly spin-orbit coupled systems
Annotation in Czech
The goal of this predominantly experimental project is to achieve an efficient magnetization manipulation in systems with strong spin-orbit interaction by means of optically-assisted spin-orbit torque. The combination of current-induced magnetization dynamics with its magneto-optical detection will allow understanding in detail the underlying mechanism of spin-orbit torque in the particular structure. The effect of of light-induced heating on the SOT symmetry will be studied in the systems of interest in order to achieve further improvement of the SOT efficiency, and the optimum system will be studied to facilitate an all-optical spin-orbit based magnetization manipulation.

Project results evaluation
The effect of „spin-orbit torque“ in heterostructures of a ferromagnet and a system with a strong spin-orbit coupling was studied. The all-optical spin orbit torque in these structures was experimentally demonstrated. The systems suitable for an efficient manipulation with magnetization using SOT were identified. The artefacts affecting major part of the opto-transport experiments were also described.
