  • Magnetization reversal in magnetic topological insulators drives quantum phase transitions between quantum anomalous Hall, axion insulator, and normal insulator states. Using novel analysis protocol, the authors investigate critical behaviours of these transitions and establish their electronic origin.

  • In quantum anomalous Hall (QAH) materials, the mesoscopic scattering length (Ls) plays an instrumental role in determining transport properties. Here, the authors examine Ls in three regimes (QAH, quantum critical, and insulating) with distinct transport behaviours, and find a universal Ls across all regimes.

  • Emergent quantum phenomena such as quantized anomalous Hall effect may be realized in magnetic topological materials. Here, Hu et al. discovered an intrinsic natural heterostructural Z2 antiferromagnetic topological insulator MnBi4Te7 with low out-of-plane saturation fields.
