We also find that, for systems with "antiferromagnetic symmetry," there is a Z2 classification in three-dimensions, and hence a class of "antiferromagnetic topological insulators" (AFTIs) which are distinguished from ordinary antiferromagnets. From the perspective of the bulk, AFTI exhibits the ...
613Citations 8Altmetric Metrics Abstract The intricate interplay between non-trivial topology and magnetism in two-dimensional materials can lead to the emergence of interesting phenomena such as the quantum anomalous Hall effect. Here we investigate the quantum transport of both bulk crystal and exfolia...
(H|| c) measured at 0.1 T. The abrupt halt in the rise ofxcon cooling suggests the onset of AFM ordering, similar to that seen in other vdW antiferromagnets MnBi2Te4and CrCl3,9,28but different from the FM one29, suggesting that long range AFM ordering takes place at 13 K. This ...
On the other hand, the intrinsic AHE is due to Berry curvature ink-space and thus it naturally includes topological aspects of the band structure, so could be viewed as ‘topological’. It has also been shown that in kagome ferromagnets the AHE can be understood as an effective ‘THE’ due...
