Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators

Thiago R. F. Peixoto, Hendrik Bentmann, Philipp Rüßmann +27

Since the discovery of the quantum anomalous Hall effect in the magnetically doped topological insulators (MTI) Cr:(Bi,Sb) $_{2}$ Te $_{3}$ and V:(Bi,Sb) $_{2}$ Te $_{3}$ , the search for the exc…

Orbital-driven Rashba effect in a binary honeycomb monolayer AgTe

Maximilian Ünzelmann, Hendrik Bentmann, Philipp Eck +12

The Rashba effect is fundamental to the physics of two-dimensional electron systems and underlies a variety of spintronic phenomena. It has been proposed that the formation of Rash…

Topological electronic structure and intrinsic magnetization in MnBi $_{4}$ Te $_{7}$ : a Bi $_{2}$ Te $_{3}$ -derivative with a periodic Mn sublattice

Raphael C. Vidal, Alexander Zeugner, Jorge I. Facio +23

Combinations of non-trivial band topology and long-range magnetic order hold promise for realizations of novel spintronic phenomena, such as the quantum anomalous Hall effect and t…

Surface states and Rashba-type spin polarization in antiferromagnetic MnBi $_{2}$ Te $_{4}$

R. C. Vidal, H. Bentmann, T. R. F. Peixoto +32

The layered van der Waals antiferromagnet MnBi $_{2}$ Te $_{4}$ has been predicted to combine the band ordering of archetypical topological insulators such as Bi $_{2}$ Te $_{3}$ with the magnet…

Chemical Aspects of the Antiferromagnetic Topological Insulator MnBi $_{2}$ Te $_{4}$

Alexander Zeugner, Frederik Nietschke, Anja U. B. Wolter +25

Crystal growth of MnBi $_{2}$ Te $_{4}$ has delivered the first experimental corroboration of the 3D antiferromagnetic topological insulator state. Our present results confirm that th…
