Research Interests
Christoph’s research focusses on spin dynamics and the generation, control, and detection of spin currents in magnetic multilayers using x-ray detected ferromagnetic resonance. He also studies emergent chirality in complex multiferroic materials and is involved in the investigation of polar skyrmions based on resonant soft x-ray scattering.
