Observation of the sliding phason mode of the incommensurate magnetic texture in Fe/Ir(111)
Hung-Hsiang Yang, Louise Desplat, Volodymyr P. Kravchuk +6
The nanoscopic magnetic texture forming in a monolayer of iron on the (111) surface of iridium, Fe/Ir(111), is spatially modulated and uniaxially incommensurate with respect to the…
Friedel Oscillations and superconducting-gap enhancement by impurity scattering
Matthias Stosiek, Clemens Baretzky, Timofey Balashov +2
Experiments observe an enhanced superconducting gap over impurities as compared to the clean-bulk value. In order to shed more light on this phenomenon, we perform simulations with…
A compact ultrahigh vacuum scanning tunneling microscope with dilution refrigeration
Timofey Balashov, Michael Meyer, Wulf Wulfhekel
We have designed and built a scanning tunneling microscope (STM) setup for operation at millikelvin temperatures in ultra high vacuum. A compact cryostat with an integrated dilutio…
Large Tunneling Anisotropic Magnetoresistance mediated by Surface States
Marie Hervé, Timofey Balashov, Arthur Ernst +1
We investigated the tunneling anisotropic magnetoresistance (TAMR) in thick hcp Co films at cryogenic temperatures using scanning tunneling microscopy. At around -350 mV, a strong…
Electron-assisted magnetization tunneling in single spin systems
Timofey Balashov, Christian Karlewski, Tobias Märkl +2
Magnetic excitations of single atoms on surfaces have been widely studied experimentally in the past decade. Lately, systems with unprecedented magnetic stability started to emerge…
Magnetic adatoms as memory bits: A quantum master equation analysis
Christian Karlewski, Michael Marthaler, Tobias Märkl +3
Due to underlying symmetries the ground states of magnetic adatoms may be highly stable, which opens perspectives for application as single-atom memory. A specific example is a sin…
Correlated Electrons Step-by-Step: Itinerant-to-Localized Transition of Fe Impurities in Free-Electron Metal Hosts
C. Carbone, M. Veronese, P. Moras +10
High-resolution photoemission spectroscopy and realistic ab-initio calculations have been employed to analyze the onset and progression of d-sp hybridization in Fe impurities depos…
Magnetic Anisotropy and Magnetization Dynamics of Individual Atoms and Clusters of Fe and Co on Pt(111)
T. Balashov, T. Schuh, A. F. Takacs +8
The recently discovered giant magnetic anisotropy of single magnetic Co atoms raises the hope of magnetic storage in small clusters. We present a joint experimental and theoretical…
