Hedgehog-like spin texture in Sb-doped MnBiTe
Meng Zeng, Shu Mo, Ke Zhang +13
We employ spin- and angle-resolved photoemission spectroscopy and circular-dichroism ARPES to systematically investigate the spin texture of Sb-doped MnBiTe. Our results di…
Observation of floating surface state in obstructed atomic insulator candidate NiP
Xiang-Rui Liu, Ming-Yuan Zhu, Yuanwen Feng +15
Obstructed atomic insulator is recently proposed as an unconventional material, in which electric charge centers localized at sites away from the atoms. A half-filling surface stat…
Observation of Spin Splitting in Room-Temperature Metallic Antiferromagnet CrSb
Meng Zeng, Ming-Yuan Zhu, Yu-Peng Zhu +18
Recently, unconventional antiferromagnets that enable the splitting of electronic spins have been theoretically proposed and experimentally realized, where the magnetic sublattices…
Pressure-tuned intralayer exchange in superlattice-like MnBi2Te4/(Bi2Te3)n topological insulators
Jifeng Shao, Yuntian Liu, Meng Zeng +13
The magnetic structures of MnBi2Te4(Bi2Te3)n can be manipulated by tuning the interlayer coupling via the number of Bi2Te3 spacer layers n, while the intralayer ferromagnetic (FM)…
Half-Magnetic Topological Insulator
Ruie Lu, Hongyi Sun, Shiv Kumar +21
Topological magnets are a new family of quantum materials providing great potential to realize emergent phenomena, such as quantum anomalous Hall effect and axion-insulator state.…
Spectroscopic realization of large surface gap in a doped magnetic topological insulator
Xiao-Ming Ma, Yufei Zhao, Ke Zhang +25
Realization of the quantum anomalous Hall effect and axion electrodynamics in topological materials are among the paradigmatic phenomena in condensed matter physics. Recently, sign…
