Research and Projects on Magnetization Dynamics and Nanomagnetism

Research group Dr. Kilian Lenz

People:

Gruppenbild FWIN-D


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.
