One-Dimensional Edge Transport in Few-Layer WTe
Artem Kononov, Gulibusitan Abulizi, Kejian Qu +5
WTe is a layered transitional-metal dichalcogenide (TMD) with a number of intriguing topological properties. Recently, WTe has been predicted to be a higher-order topologic…
Intrinsic axion insulating behavior in antiferromagnetic MnBiTe
Na Hyun Jo, Lin-Lin Wang, Robert-Jan Slager +6
A striking feature of time reversal symmetry (TRS) protected topological insulators (TIs) is that they are characterized by a half integer quantum Hall effect on the boundary when…
Magnetic imaging of antiferromagnetic domain walls
Paul M. Sass, Wenbo Ge, Jiaqiang Yan +3
The control of domain walls or spin textures is crucial for spintronic applications of antiferromagnets. Despite many efforts, it has been challenging to directly visualize antifer…
A-type Antiferromagnetic order in MnBi4Te7 and MnBi6Te10 single crystals
J. -Q. Yan, Y. H. Liu, D. Parker +5
MnBiTe and MnBiTe are two members with n=2 and 3 in the family of MnBiTe where the n=1 member, MnBiTe, has been intensively investiga…
Gapless Dirac surface states in the antiferromagnetic topological insulator MnBi2Te4
Przemyslaw Swatek, Yun Wu, Lin-Lin Wang +4
We use high-resolution, tunable angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations to study the electronic properties of single crys…
Quasi 2-D magnetism in the Kagome layer compound FeSn
Brian C. Sales, Jiaqiang Yan, William R. Meier +3
Single crystals of the single Kagome layer compound FeSn are investigated using x-ray and neutron scattering, magnetic susceptibility and magnetization, heat capacity, resistivity,…
