This week, we welcome Nadine Hauptmann from Radboud University in Nijmegen as our seminar guest. She is a specialist in scanning probe microscopy and works in the group of Alexander Khajetoorians. We are looking forward to her presentation about the new probing capabilities of SPEX (spin-polarized scanning tunneling microscopy combined with magnetic exchange force microscopy) applied to the ultrathin film system Fe/Ir(111), where nano-skyrmions or spin spirals occur depending on the number of Fe-layers.
