The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Feasibility of many emergent phenomena that intrinsic magnetic topological insulators (TIs)
may host depends crucially on our ability to engineer and efficiently tune their electronic and …

Topological states of matter possess bulk electronic structures categorized by topological
invariants and edge/surface states due to the bulk-boundary correspondence. Topological …

Novel magnetic topological materials pave the way for studying the interplay between band
topology and magnetism. However, an intrinsically ferromagnetic topological material with …

Here, we present microscopic evidence of the persistence of uniaxial A-type
antiferromagnetic order to the surface layers of MnBi 2 Te 4 single crystals using magnetic …

Many experiments observed a metallic behavior at zero magnetic fields (antiferromagnetic
phase, AFM) in MnBi 2 Te 4 thin film transport, which coincides with gapless surface states …

Axion, first postulated as a hypothetical particle in high-energy physics, is now extended to
describe a novel topological magnetoelectric effect derived from the Chern–Simons theory …

Using angle-resolved photoelectron spectroscopy (ARPES), we investigate the surface
electronic structure of the magnetic van der Waals compounds MnBi 4 Te 7 and MnBi 6 Te …

Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of
quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana …

Despite the rapid progress in understanding the first intrinsic magnetic topological insulator
MnBi 2 Te 4, its electronic structure remains a topic under debates. Here we perform a …
