At the Walther-Meissner-Institute we use this technique to investigate the magnetic properties of bulk materials, thin film systems and multilayer systems. This allows us to quantify static magnetic properties like the saturation magnetization, magnetic anisotropies and the type of the magnetic order. In addition, this technique allows to study the dynamical properties of magnetic excitations like magnetic damping.

We are also developing and using techniques with are employ the excitation of the magnetic system using magnetic resonance techniques and complement those with electronic or optical readout concepts. This allows to address questions regarding the excitation and detection of spin currents and the spatially propagation on spin excitations.
