Detuning the Honeycomb of the α-RuCl3 Kitaev lattice: A case of Cr3+ dopant
Maria Roslova, Jens Hunger, Gaël Bastien +9
Fine-tuning chemistry by doping with transition metals enables new perspectives for exploring Kitaev physics on a two-dimensional (2D) honeycomb lattice of α-RuCl3, which is promis…
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…
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…
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…
Large Thermal Hall Effect in -RuCl: Evidence for Heat Transport by Kitaev-Heisenberg Paramagnons
Richard Hentrich, Maria Roslova, Anna Isaeva +4
The honeycomb Kitaev model in a magnetic field is a source of a topological quantum spin liquid with Majorana fermions and gauge flux excitations as fractional quasiparticles. We p…
