Zero-field chiral edge transport in an intrinsic magnetic topological insulator MnBi₂Te₄.

ABSTRACT: The Dissipationless chiral edge state (CES) stands as a pivotal feature in quantum anomalous Hall (QAH) insulators. The dissipationless nature and chirality give rise to unique transport properties and provide insights into future electronics and spintronics. In recent years, a new van der Waals intrinsic magnetic topological insulator, MnBi₂Te₄ (MBT), has attracted significant research interests. The quantum anomalous Hall effect has been successfully achieved in odd-layer MBT. However, few studies can reproduce the zero-field quantization due to poor sample quality, and as a result, the transport properties of CES have rarely been explored in a well quantized MBT sample at zero magnetic field. Here, we report an electrical transport study of CES in a 5-septuple laye
