Quantum anomalous hall insulator
Quantum anomalous Hall effect (QAHE) is the "quantum" version of the anomalous Hall effect. While the anomalous Hall effect requires a combination of magnetic polarization and spin-orbit coupling to generate a finite Hall voltage even in the absence of an external magnetic field (hence called "anomalous"), the quantum anomalous Hall effect is its quantized version. The Hall conductivity acquires quantized values proportional to integer multiples of the von Klitzing const… WebMagnetic topological insulators, such as MnBi 2 Te 4 have attracted great attention recently due to their application to the quantum anomalous Hall (QAH) effect.
