Magnetization and Spin Dynamics

ICON arrow right Magnetism and Spintronics
The study of the dynamic response of both interacting and non-interacting spin systems provides important input for the general understanding of magnetic materials. Moreover, this dynamic response can be harnessed for generating spin currents, manipulating magnon transport, or laying the foundation of self-oscillations in magnetic devices.

We study the dynamics of both paramagnetic and exchange-coupled spin systems by broadband magnetic resonance spectroscopy. We aim at extracting fundamental material parameters like magnetic anisotropy, exchange coupling and damping of spin dynamics in a wide range of materials, ranging from simple ferromagnets to topologically nontrivial magnets with complex spin textures. A particular focus of our research is the study and application of spin-orbit torques.
