Dr. Marcus Wyss

Dr. Marcus Wyss started as a Ph.D. student in April of 2014 after completing a Masters degree in the group of Prof. Laura Heyderman under supervision of Prof. Frithjof Nolting, both at the Paul Scherrer Institute (PSI). He pursued a number of nano-magnetic imaging projects including x-ray magnetic circular dichroism photoemission electron microscopy (XMCD-PEEM) experiments at PSI and scanning SQUID microscopy (SSM) experiments in the Poggio lab. He later used both XMCD-PEEM and SSM to study ferromagnetic nanotubes and SSM to study artificial spin ice. He graduated in November 2018 and started working as a post-doc in the Poggio lab and on a new design for SQUID-on-tip sensors for the next generation of SSM, which confirmed the general feasibility and paving the way for the FIBsuperProbes project. He is responsible for the administration concerning the project.
