Hybridization-Induced Gapped and Gapless States on the Surfaces of Magnetic Topological Insulators

Xiao-Ming Ma, Zhongjia Chen, Eike F. Schwier +25

The layered MnBi2nTe3n+1 family represents the first intrinsic antiferromagnetic topological insulator (AFM TI, protected by a combination symmetry ) ever discovered, providing an…
