Who We Are

The position is assigned to the workgroup Kuch, which has experience investigating ultrathin magnetic films, surfaces, nanostructures, and adsorbed molecules that may become relevant in a future spin-based electronics. A focus is on spin and magnetization dynamics of ultrathin layers with unconventional spin structures and on the magnetism of adsorbed molecules. Experiments are carried out both by laboratory-based techniques as well as by using synchrotron radiation.

What You Can Expect in Your New Role

The PhD-thesis project encompasses time- and element-resolved X-ray-spectroscopy investigations of magnetic layered systems with interfaces between layers of different spin structures. The position is embedded in a research project funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) as part of the Transregional Collaborative Research Center 227 "Ultrafast Spin Dynamics". The goal is to gain insight into the interplay of ultrafast demagnetization, transient spin currents, and thermal effects after ultrafast optical excitation. Circular and linear magnetic dichroism in resonant x-ray reflectivity help to reveal the temporal evolution of ferromagnetic and antiferromagnetic spin structures as a function of depth in the layers. Experiments will be carried out in the university laboratory in Berlin-Dahlem and at the synchrotron-radiation source BESSY II in Berlin-Adlershof.

Key Requirements

A Master's degree is required with a Master's thesis in experimental physics or equivalent.

Desirable

Experience in magnetization dynamics, ultrafast pump–probe experiments, surface science, ultra-high vacuum, or x-ray absorption spectroscopy of magnetic materials.
