Electronic States and Magnetic Response of MnBi<sub>2</sub>Te<sub>4</sub> by Scanning Tunneling Microscopy and Spectroscopy
Exotic quantum phenomena have been demonstrated in recently discovered intrinsic magnetic topological insulator MnBi2Te4. At its two-dimensional limit, the quantum anomalous Hall effect and axion insulator state were observed in odd and even layers of MnBi2Te4, respectively. Here, we employ low-temperature scanning tunneling microscopy to study the electronic properties of …
