Publication in Electrochimica Acta
Our manuscipt on nanoscale iron films by self-terminated electrodeposition has been accepted for publication in Electrochimica Acta! Here, we investigated the fundamental processes during self-termination of nanoscale iron films by combining electrochemical quartz microbalance measurements and model calculations based on diffusion theory. We found interesting catalytic effects related to the Fe(OH)2/Fe interface formation and enhanced stability of the self-terminated films.Congratulation to Martin! doi.org/10.1016/j.electacta.2022.140170

Group workshop and Welcome to Dr. Piotr Graczyk
We had two intense days of talks, discussion and future planning of research and teaching activities at TUC. A walk to the castle and lunch at the Turm-Brauhaus was fun, too. We welcome Dr. Piotr Graczyk from the Adam Mickiwiecz University and the Institute of Molecular Physics, Polish Academy of Sciences, Poznan, Poland as a guest scientist in our group. In his 5 month research stay he will investigate voltage-control of magnetic films using our in situ Kerr microscope.

Our brand new Kerr microscope arrived
Our new Kerr microscope arrived and is now installed. We are excited to start using it to characterize the magnetic microstructures of thin films and nanostructures. Especially, we will use it together with a home-built electrochemical in situ cell to investigate the impact of liquid electrolyte gating on the magnetic response, i.e. to study magneto-ionic materials for voltage control magnetism. See examples of what can be done here: DOI: doi.org/10.1002/aelm.202000406.
