Anomalous and Topological Hall Effects in Antiferromagnetic EuSn2As2 Nanostructures
Evgeny I. Maltsev, Nicolas Pérez, Romain Giraud +8
We investigate magnetotransport in exfoliated nanostructures of the candidate magnetic 3D topological insulator . Similar to macroscopic single crystals, t…
Transport evidence of surface states in magnetic topological insulator MnBi2Te4
Michael Wissmann, Romain Giraud, Börge Mehlhorn +8
Magnetic topological insulators can host chiral 1D edge channels at zero magnetic field, when a magnetic gap opens at the Dirac point in the band structure of 2D topological surfac…
Non-Hermitian topological devices with Chern insulators
Kyrylo Ochkan, Michael Wissmann, Louis Veyrat +9
Multi-terminal topological devices are a new generation of electronic devices with quantized properties robust against imperfections. In magnetic topological insulators, dissipatio…
Giant universal conductance fluctuations in the antiferromagnetic topological insulator MnBi2Te4
Michael Wissmann, Joseph Dufouleur, Louis Veyrat +4
Intrinsic magnetic topological insulators can host quantum states with quantized magneto-electric responses, such as the axion and Chern insulators states evidenced in ultra-thin M…
Room temperature Planar Hall effect in nanostructures of trigonal-PtBi2
Arthur Veyrat, Klaus Koepernik, Louis Veyrat +13
Trigonal-PtBi2 has recently garnered significant interest as it exhibits unique superconducting topological surface states due to electron pairing on Fermi arcs connecting bulk Wey…
Fermi surface evolution in Weyl semimetal t-PtBi probed by transverse transport properties
F. Caglieris, M. Ceccardi, D. Efremov +8
The combination of non-trivial topology and superconductivity opens to novel quantum devices. The discovery of intrinsic materials where such properties appear together represents…
