Description:
The research topics of work group covers both the static magnetic properties (e.g. magnetization, anisotropy, coercivity, interlayer exchange coupling) as well as dynamic properties like, linewidth and precessional damping effects, spin-torque effects, etc.
The investigations are caried out using ferromagnetic resonance (FMR), magnetooptical Kerr effect (MOKE), and SQUID magnetometry. Details of the setups can be found here.
Projects:
- Hybrid Magnetic Materials: microscopic origin – macroscopic results
- Morphology induced magnetic correlation effects in mesoscopic wire and island structures
- Magnetism of nanoscale CoCrPt-SiO2 Films in geometrically confined dimensions
- Dynamics of spin textures
