Ultrafast electron dynamics upon above band-gap excitation in epitaxial LaFeO(001) thin films
Friederike Elisa Wührl, Antonia Rieche, Anne Oelschläger +2
Strong electron correlations in perovskite oxides give rise to rich and often unexpected electronic phenomena. In this study, we present a comprehensive surface-science investigati…

Time-resolved electron dynamics in antiferromagnetic CoO(001) thin films
Mathias Augstein, Friederike Wührl, Konrad Gillmeister +2
Ultrathin antiferromagnetic CoO(001)-(1x1) films of 2 and 4 monolayers (ML) on Ag(001) are investigated by time- and angle-resolved two-photon photoelectron (2PPE) spectroscopy. Pu…

Improved imaging of magnetic domains with a photoelectron emission microscope by utilizing symmetry and momentum selection
F. O. Schumann, M. Paleschke, J. Henk +2
Imaging of magnetic domains with a photoelectron emission microscope operated with photon energies in the threshold regime often suffers from low contrast. In this work we show by…
