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…
Tunning the number of chiral edge channels in a fixed quantum anomalous Hall system
Peng Deng, Yulei Han, Peng Zhang +3
Quantum anomalous Hall (QAH) insulators exhibit chiral edge channels characterized by vanishing longitudinal conductance and quantized Hall conductance of Ce2/h, wherein the Chern…
Implementing Microwave Impedance Microscopy in a Dilution Refrigerator
Zhanzhi Jiang, Su Kong Chong, Peng Zhang +5
We report the implementation of a dilution-refrigerator-based scanning microwave impedance microscope (MIM) with a base temperature of ~ 100 mK. The vibration noise of our apparatu…
Structural tuning magnetism and topology in a magnetic topological insulator
Christopher Eckberg, Gang Qiu, Tao Qu +10
To date, the most widely-studied quantum anomalous Hall insulator (QAHI) platform is achieved by dilute doping of magnetic ions into thin films of the alloyed tetradymite topologic…
Anomalous Landau quantization in intrinsic magnetic topological insulators
Su Kong Chong, Chao Lei, Seng Huat Lee +4
The intrinsic magnetic topological insulators, Mn(Bi1-xSbx)2Te4, in their spin-aligned strong field configuration have been identified as a Weyl semimetal with single pair of Weyl…
