Magnetotransport properties in MnBi<sub>2n</sub>Te<sub>3n+1</sub>

ORAL

Abstract

Recently, magnetic topological insulators MnBi2nTe3n+1 were discovered, where quantized anomalous hall resistance was observed in the two-dimensional limit of MnBi2Te4 at a record high temperature of 4 K under 12 T, providing an important material platform to explore emergent quantum phenomena such as quantized anomalous Hall effect and Majorana modes, etc. MnBi2nTe3n+1 family is made of alternating one septuple [MnBi2Te4] and (n-1) quintuple [Bi2Te3] layers, where the interlayer magnetic couplings are tuned systematically with increasing n. In this talk, we will show our recent results on the magentotransport properties in MnBi2nTe3n+1, shedding light on the interplay between magnetism and band topology.
