Pressure-tunable phase transitions in atomically thin Chern insulator MnBi${}_2$Te${}_4$

Albin Marffy, Endre Tovari, Yu-Fei Liu +8

Topological insulators lacking time-reversal symmetry can exhibit the quantum anomalous Hall effect. Odd-layer thick MnBi${}_2$Te${}_4$ is a promising platform due to its intrinsic mag…
