Nanoscale Surface Dynamics of BiTe(111): Observation of a Prominent Surface Acoustic Wave and the Role of van der Waals Interactions
Anton Tamtögl, Davide Campi, Martin Bremholm +8
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator BiTe. Using high-resolution helium-3 spin-echo spectr…

A Helium-Surface Interaction Potential of BiTe(111) from Ultrahigh-Resolution Spin-Echo Measurements
Anton Tamtögl, Michael Pusterhofer, Martin Bremholm +7
We have determined an atom-surface interaction potential for the HeBiTe(111) system by analysing ultrahigh resolution measurements of selective adsorption resonances. Th…

Reorientation of the bicollinear antiferromagnetic structure at the surface of FeTe bulk and thin films
Torben Hänke, Udai Raj Singh, Lasse Cornils +10
Establishing the relation between the ubiquitous antiferromagnetism in the non-superconducting parent compounds of unconventional superconductors and their superconducting phase is…
