Wegner Group: Nanoscale Magnetism & Electronics

 
 

We are a condensed matter research team within the Scanning Probe Microscopy (SPM) group (headed by Prof. Alex Khajetoorians) at the Institute for Molecules and Materials of Radboud University Nijmegen, Netherlands. We focus on the study of electronic and magnetic properties of surfaces and nanoscopic materials down to single molecules and atoms using scanning probe techniques. Our laboratories can be found in the NanoLab.

We kindly acknowledge funding by the DFG (Germany) through the Emmy Noether program as well as by FOM (Netherlands). More information on our research activities and publications can be found here:
