Magnetic-field-induced robust zero Hall plateau state in MnBi2Te4 Chern insulator

Magnetic-field-induced robust zero Hall plateau state in MnBi2Te4 Chern insulator

The antiferromagnetic topological insulator MnBi2Te4 exhibits Chern and axion insulator phases at low magnetic field; however, its behaviour in high magnetic field has remained unexplored. Here, using transport measurements at high magnetic field, the authors report a zero Hall plateau composed of t...

Magnetic-field-induced robust zero Hall plateau state in MnBi2Te4 Chern insulator
description The antiferromagnetic topological insulator MnBi2Te4 exhibits Chern and axion insulator phases at low magnetic field; however, its behaviour in high magnetic field has remained unexplored. Here, using transport measurements at high magnetic field, the authors report a zero Hall plateau composed of two counter-propagating edge channels.
