Scanning Tunneling Spectroscopy of Subsurface Ag and Ge Impurities in Copper
Thomas Kotzott, Mohammed Bouhassoune, Henning Prüser +3
We investigate single Ge and Ag impurities buried below a Cu(100) surface using low temperature scanning tunneling microscopy. The interference patterns in the local density of sta…
Friedel oscillations induced by magnetic skyrmions: from scattering properties to all-electrical detection
Mohammed Bouhassoune, Samir Lounis
Magnetic skyrmions are spin swirling solitonic defects that can play a major role in information technology. Their future in applications and devices hinges on their efficient mani…
Defect-implantation for the all-electrical detection of non-collinear spin-textures
Imara Lima Fernandes, Mohammed Bouhassoune, Samir Lounis
The viability of past, current and future devices for information technology hinges on their sensitivity to the presence of impurities. The latter can lead to resistivity anomalies…
Comparison of first-principles methods to extract magnetic parameters in ultra-thin films: Co/Pt(111)
Bernd Zimmermann, Gustav Bihlmayer, Marie Böttcher +6
We compare three distinct computational approaches based on first-principles calculations within density functional theory to explore the magnetic exchange and the Dzyaloshinskii-M…
Unoccupied surface and interface states in Pd thin films deposited on Fe/Ir(111) surface
Mohammed Bouhassoune, Imara L. Fernandes, Stefan Blügel +1
We present a systematic first-principles study of the electronic surface states and resonances occuring in thin films of Pd of various thicknesses deposited on a single ferromagnet…
Chirality-driven orbital magnetic moments as a new probe for topological magnetic structures
Manuel dos Santos Dias, Juba Bouaziz, Mohammed Bouhassoune +2
When electrons are driven through unconventional magnetic structures, such as skyrmions, they experience emergent electromagnetic fields that originate several Hall effects. Indepe…
Perpendicular Reading of Single Confined Magnetic Skyrmions
Dax M. Crum, Mohammed Bouhassoune, Juba Bouaziz +3
Thin-film sub-5 nm magnetic skyrmions constitute an ultimate scaling alternative for future digital data storage. Skyrmions are robust non-collinear spin-textures that can be moved…
Quantum well states and amplified spin-dependent Friedel oscillations in thin films
Mohammed Bouhassoune, Bernd Zimmermann, Phivos Mavropoulos +4
Electrons mediate many of the interactions between atoms in a solid. Their propagation in a material determines its thermal, electrical, optical, magnetic and transport properties.…
Interplay between Kondo effect and Ruderman-Kittel-Kasuya-Yosida interaction
Henning Prüser, Piet E. Dargel, Mohammed Bouhassoune +4
The interplay between the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction and the Kondo effect is expected to provide the driving force for the emergence of many phenomena in stro…
Theoretical probing of inelastic spin-excitations in adatoms on surfaces
Samir Lounis, Benedikt Schweflinghaus, Manuel dos Santos Dias +3
We review our recent work on the simulation, description and prediction of spin-excitations in adatoms and dimers deposited on metallic surfaces. This work done together with Dougl…
Spin excitations of individual Fe atoms on Pt(111): impact of the site-dependent giant substrate polarization
Alexander Ako Khajetoorians, Tobias Schlenk, Benedikt Schweflinghaus +6
We demonstrate using inelastic scanning tunneling spectroscopy (ISTS) and simulations based on density functional theory that the amplitude and sign of the magnetic anisotropy ener…
