Magnetic properties of molecular beam epitaxy-grown ultrathin Cr2Ge2Te6 films down to monolayer limit on Si substrates
Pengfei Ji, Ruixuan Liu, Tianchen Zhu +13
Cr2Ge2Te6, a prototypical van der Waals ferromagnetic semiconductor, have attracted significant interest for its potential applications in high-performance spintronics. However, th…
Universally optimizable strategy for magnetic gaps towards high-temperature quantum anomalous Hall states via magnetic-insulator/topological-insulator building-blocks
Zhe Li, Feng Xue, Xin-Yi Tang +4
Optimizing the magnetic Zeeman-splitting term, specifically the magnetic gap of the topological surface states (TSSs), is a crucial issue and central challenge in advancing higher-…
Chern insulator phase realized in dual-gate-tuned MnBi2Te4 thin films grown by molecular beam epitaxy
Yunhe Bai, Yuanzhao Li, Ruixuan Liu +19
The intrinsic magnetic order, large topological-magnetic gap and rich topological phases make MnBi2Te4 a wonderful platform to study exotic topological quantum states such as axion…
Interplay between electronic dephasing and localization in finite-sized Chern insulator
Yunhe Bai, Yuanzhao Li, Jianli Luan +14
Anderson localization is anticipated to play a pivotal role in the manifestation of the quantum anomalous Hall effect, akin to its role in conventional quantum Hall effects. The si…
Correlation between magnetic domain structures and quantum anomalous Hall effect in epitaxial MnBi2Te4 thin films
Yang Shi, Yunhe Bai, Yuanzhao Li +16
We use magnetic force microscopy (MFM) to study spatial uniformity of magnetization of epitaxially grown MnBi2Te4 thin films. Compared to films which exhibit no quantum anomalous H…
Reentrant quantum anomalous Hall effect in molecular beam epitaxy-grown MnBi2Te4 thin films
Yuanzhao Li, Yunhe Bai, Yang Feng +16
In this study, we investigate intrinsic magnetic topological insulator MnBi2Te4 thin films grown by molecular beam epitaxy. We observe a reentrant quantum anomalous Hall effect whe…
