Quantum Anomalous Hall Effect in Perfectly Compensated Collinear Antiferromagnetic Thin Films
Chao Lei, Olle Heinonen, R. J. McQueeney +1
We show that the quantum anomalous Hall effect almost always occurs in magnetic topological insulator thin films whenever the top and bottom surface layer magnetizations are parall…
Low temperature competing magnetic energy scales in the topological ferrimagnet TbMn6Sn6
S. X. M. Riberolles, Tyler J. Slade, D. L. Abernathy +7
TbMn6Sn6 is a metallic ferrimagnet displaying signatures of both topological electrons and topological magnons arising from ferromagnetism and spin-orbit coupling within its Mn kag…
Evolution of Magnetic Interactions in Sb-substituted MnBi2Te4
S. X. M. Riberolles, Q. Zhang, Elijah Gordon +4
The Mn(BiSb)Te series is purported to span from antiferromagnetic (AF) topological insulator at x = 0 to a trivial AF insulator at x = 1. Here we report on neut…
Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting
S. -K. Bac, K. Koller, F. Lux +15
Three-dimensional (3D) compensated MnBi2Te4 is antiferromagnetic, but undergoes a spin-flop transition at intermediate fields, resulting in a canted phase before saturation. In thi…
Carrier Tuning of Stoner Ferromagnetism in ThCrSi-Structure Cobalt Arsenides
B. G. Ueland, Santanu Pakhira, Bing Li +7
CaCoAs is an unusual itinerant magnet with signatures of extreme magnetic frustration. The conditions for establishing magnetic order in such itinerant frustrated magne…
Metamagnetism of few layer topological antiferromagnets
C. Lei, O. Heinonen, A. H. MacDonald +1
MnBiTe (MBT) is a promising antiferromagnetic topological insulator whose films provide access to novel and technologically important topological phases, including quantum…
