Department Spin and Topology in Quantum Materials

Research topics

The research program within the department covers practically all basic phenomena that lay the ground  for future spintronics. These phenomena are investigated at various length, time, energy and temperature scales at the synchrotron radiation source BESSY by means of Photoemission electron microscopy (PEEM), angled-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM). This in-house research is related to two topics within POF III (Programme Oriented Funding from the Helmholtz Association) , namely i) Research with large scale facilities, and ii)  Future Information Technologies
