Magnetism & Spintronics: Spin Dynamics

Spin Dynamics
We study the dynamics of paramagnets and exchangecoupled spin systems by magnetic resonance spectroscopy. We are interested in extracting fundamental material parameters like magnetic damping, anisotropy and exchange in a wide range of material classes. Furthermore, we apply broadband magnetic resonance to study dynamics of topologically nontrivial magnets and spinorbit torques. Experimental facilities include:
 Broadband, coplanar waveguide based magnetic resonance in a frequency range up to 50 GHz and magnetic fields up to 2.7 T provided by a roomtemperature electromagnet
 3D vectormagnet cryostat capable of applying up to 2.5 T in any direction, with temperature ranging from 1.7 K to 300 K and frequency up to 50 GHz.
 Broadband magnetic resonance at ultralow temperatures (below 100 mK)
 Quantitative phaseresolved magnetic resonance using vector network analysis
 Cavity based magnetic resonance at 10 GHz and 24 GHz with temperatures from 4 K to 300 K
 Frequencyresolved magnetooptic Kerr effect for spatially resolved magnetic resonance studies at room temperature
 Access to a micro focused roomtemperature Brillouin Light Scattering facility through the Nanosystems Initiative Munich (NIM).
