Electronic Correlations Control Interlayer Coupling and Magnetic Transition in MnBi${}_2$Te${}_4$/MnBr${}_3$ Heterostructure

Yuanhao Zhu, Xixi Yuan, Ying Zhao +3

Bulk MnBi${}_2$Te${}_4$ (MBT) is an intrinsic antiferromagnetic topological insulator. However, its low Néel temperature of $\sim 25\mathrm{K}$ severely restricts its practical appli…
