Topological electronic structure and intrinsic magnetization in MnBiTe: a BiTe-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…
Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
Designing 3D topological insulators by 2D-Xene (X = Ge, Sn) sheet functionalization in the GaGeTe-type structures
Florian Pielnhofer, Tatiana V. Menshchikova, Igor P. Rusinov +10
State-of-the-art theoretical studies anticipate a 2D Dirac system in the "heavy" analogues of graphene, free-standing buckled honeycomb-like Xenes (X = Si, Ge, Sn, Pb, etc.). Herew…
Coexisting surface states in the weak and crystalline topological insulator Bi_2TeI
Nurit Avraham, Andrew Norris, Yan Sun +7
The established diversity of electronic topology classes lends the opportunity to pair them into dual topological complexes. Bulk-surface correspondence then ensures the coexistenc…
Possible Experimental Realization of a Basic Z2 Topological Semimetal
Erik Haubold, Alexander Fedorov, Igor P. Rusinov +15
We report experimental and theoretical evidence that GaGeTe is a basic topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well…
Chemical Aspects of the Antiferromagnetic Topological Insulator MnBiTe
Alexander Zeugner, Frederik Nietschke, Anja U. B. Wolter +25
Crystal growth of MnBiTe has delivered the first experimental corroboration of the 3D antiferromagnetic topological insulator state. Our present results confirm that th…
