Growth of Altermagnetic α-MnTe Films: Substrate Variation and Surface Modification
M. Dittmar, L. Hirnet, H. Haberkamm +10
Manganese telluride (MnTe) in its hexagonal α-MnTe crystal structure has evolved as one of the altermagnet workhorse materials. The synthesis of MnTe thin films is highly relevant…
Tomographic Imaging of Orbital Vortex Lines in Three-Dimensional Momentum Space
T. Figgemeier, M. Ünzelmann, P. Eck +16
We report the experimental discovery of orbital vortex lines in the three-dimensional (3D) band structure of a topological semimetal. Combining linear and circular dichroism in sof…
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…
A simple recipe to create three-dimensional reciprocal space maps
Rafaela F. S. Penacchio, Maurício B. Estradiote, Sérgio L. Morelhão +5
Combinations of advanced X-ray sources and zero-noise detector of enormous dynamic range have significantly increased the opportunity of mapping the reciprocal space of crystal lat…
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…
X-ray diffraction tools for structural modeling of epitaxic films of an intrinsic antiferromagnetic topological insulator
Rafaela F. S. Penacchio, Celso I. Fornari, Yori G. Camillo +6
Synthesis of new materials demands structural analysis tools suited to the particularities of each system. Van der Waals (vdW) materials are fundamental in emerging technologies of…
Incipient antiferromagnetism in the Eu-doped topological insulator BiTe
Abdul Tcakaev, Volodymyr B. Zabolotnyy, Celso I. Fornari +14
Rare earth ions typically exhibit larger magnetic moments than transition metal ions and thus promise the opening of a wider exchange gap in the Dirac surface states of topological…
Orbital Complexity in Intrinsic Magnetic Topological Insulators MnBiTe and MnBiTe
R. C. Vidal, H. Bentmann, J. I. Facio +16
Using angle-resolved photoelectron spectroscopy (ARPES), we investigate the surface electronic structure of the magnetic van der Waals compounds MnBiTe and MnBiTe$_{10}…
