Dynamic heterogeneity in the self-induced spin glass state of elemental neodymium
L. Niggli, J. H. Strik, Z. Liu +4
Spin glasses are magnetic materials exhibiting numerous magnetization patterns, that randomly vary both in real space and in time. To date, it is still not well understood what the…
Thermally-induced magnetic order from glassiness in elemental neodymium
Benjamin Verlhac, Lorena Niggli, Anders Bergman +8
Temperature in thermodynamics is synonymous with disorder, and responsible for ultimately destroying ordered phases. Here, we show an unusual magnetic transition where, with increa…
Moiré induced electronic structure modifications in monolayer VS on Au(111)
Umut Kamber, Sahar Pakdel, Raluca-Maria Stan +11
There is immense interest in how the local environment influences the electronic structure of materials at the single layer limit. We characterize moiré induced spatial variations…
Self-induced spin glass state in elemental and crystalline neodymium
Umut Kamber, Anders Bergman, Andreas Eich +8
Spin glasses are a highly complex magnetic state of matter, intricately linked to spin frustration and structural disorder. They exhibit no long-range order and exude aging phenome…
Probing Single Vacancies in Black Phosphorus at the Atomic Level
Brian Kiraly, Nadine Hauptmann, Alexander N. Rudenko +2
Utilizing a combination of low-temperature scanning tunneling microscopy/spectroscopy (STM/STS) and electronic structure calculations, we characterize the structural and electronic…
Non-magnetic ground state of Ni adatoms on Te-terminated bismuth chalcogenide topological insulators
M. Vondracek, J. Honolka, L. Cornils +20
We report on the quenching of single Ni adatom moments on Te-terminated Bi2Te2Se and Bi2Te3 topological insulator surfaces. The effect becomes manifested as a missing X-ray magneti…
Band gap engineering by Bi intercalation of graphene on Ir(111)
Jonas Warmuth, Albert Bruix, Matteo Michiardi +7
We report on the structural and electronic properties of a single bismuth layer intercalated underneath a graphene layer grown on an Ir(111) single crystal. Scanning tunneling micr…
Controllable magnetic doping of the surface state of a topological insulator
T. Schlenk, M. Bianchi, M. Koleini +11
A combined experimental and theoretical study of doping individual Fe atoms into Bi2Se3 is presented. It is shown through a scanning tunneling microscopy study that single Fe atoms…
Robust Surface Doping of BiSe by Rb Intercalation
Marco Bianchi, Richard C. Hatch, Zheshen Li +11
Rubidium adsorption on the surface of the topological insulator BiSe is found to induce a strong downward band bending, leading to the appearance of a quantum-confined two…
Adsorbate-induced Restructuring of Pb mesas Grown on Vicinal Si(111) in the Quantum Regime
Alexander Ako Khajetoorians, Wenguang Zhu, Jisun Kim +4
Using scanning tunneling microscopy and spectroscopy, we demonstrate that the adsorption of a minute amount of Cs on a Pb mesa grown in the quantum regime can induce dramatic morph…
