Chirality-Driven Orbital Angular Momentum and Circular Dichroism in CoSi
Stefanie Suzanne Brinkman, Xin Liang Tan, Bjørnulf Brekke +15
Chiral crystals and molecules were recently predicted to form an intriguing platform for unconventional orbital physics. Here, we report the observation of chirality-driven orbital…
Strongly Anisotropic Spin and Orbital Rashba Effect at a Tellurium - Noble Metal Interface
B. Geldiyev, M. Ünzelmann, P. Eck +19
We study the interplay of lattice, spin and orbital degrees of freedom in a two-dimensional model system: a flat square lattice of Te atoms on a Au(100) surface. The atomic structu…
Intermixing-driven surface and bulk ferromagnetism in the quantum anomalous Hall candidate MnBiTe
Abdul V. Tcakaev, Bastian Rubrecht, Jorge I. Facio +19
The recent realizations of the quantum anomalous Hall effect (QAHE) in MnBiTe and MnBiTe benchmark the (MnBiTe)(BiTe) family as a promising hotb…
Topological band inversion in HgTe(001): surface and bulk signatures from photoemission
Raphael C. Vidal, Giovanni Marini, Lukas Lunczer +14
HgTe is a versatile topological material and has enabled the realization of a variety of topological states, including two- and three-dimensional (3D) topological insulators and to…
Two-dimensional ferromagnetic extension of a topological insulator
P. Kagerer, C. I. Fornari, S. Buchberger +19
Inducing a magnetic gap at the Dirac point of the topological surface state (TSS) in a 3D topological insulator (TI) is a route to dissipationless charge and spin currents. Ideally…
Simulation of X-ray diffraction in MnBiTe epitaxic films
Rafaela F. S. Penacchio, Celso I. Fornari, Yori G. Camillo +6
Disordered heterostructures stand as a general description for compounds that are part of homologous series such as bismuth chalcogenides. In device engineering, van der Waals epit…
