Electronic Structure of an Iron-Porphyrin Derivative on Au(111)
Arnulf Stein, Daniela Rolf, Christian Lotze +3
Surface-bound porphyrins are promising candidates for molecular switches, electronics and spintronics. Here, we studied the structural and the electronic properties of Fe-tetra-pyr…
Visualizing Intramolecular Distortions as the Origin of Transverse Magnetic Anisotropy
Daniela Rolf, Christian Lotze, Constantin Czekelius +2
The magnetic properties of metal-organic complexes are strongly influenced by conformational changes in the ligand. The flexibility of Fe-tetra-pyridyl-porphyrin molecules leads to…
Correlation of Kondo effect and molecular conformation of the acceptor molecule in the TTF-TCNE charge transfer complex
Paul Stoll, Christian Lotze, Janina N. Ladenthin +3
A Kondo resonance has been observed on purely organic molecules in several combinations of charge transfer complexes on a metal surface. It has been regarded as a fingerprint of th…
Tuning the coupling of an individual magnetic impurity to a superconductor: quantum phase transition and transport
Laëtitia Farinacci, Gelavizh Ahmadi, Gaël Reecht +6
The exchange scattering at magnetic adsorbates on superconductors gives rise to Yu-Shiba-Rusinov (YSR) bound states. Depending on the strength of the exchange coupling, the magneti…
Moiré structure of MoS on Au(111): Local structural and electronic properties
Nils Krane, Christian Lotze, Katharina J. Franke
Monolayer islands of molybdenum disulfide (MoS) on Au(111) form a characteristic moiré structure, leading to locally different stacking sequences at the S-Mo-S-Au interface. Us…
Control of oxidation and spin state in a single-molecule junction
Benjamin W. Heinrich, Christopher Ehlert, Nino Hatter +4
The oxidation and spin state of a metal-organic molecule determine its chemical reactivity and magnetic properties. Here, we demonstrate the reversible control of the oxidation and…
