An outstanding challenging in nanomagnetism is the quantitative understanding of magnetization reversal process of nanostructures. We investigate the magnetization reversal of individual Co islands on Cu(111). We measure switching fields H<...

When electrons are confined to nanostructures, quantum interference takes place due to their wave-particle duality. Using spin-polarized scanning tunneling microscopy, we studied the influence of quantum interference of electrons on the spatial di...
