The quantum anomalous Hall effect is defined as a quantized Hall effect realized in a system
without an external magnetic field. The quantum anomalous Hall effect is a novel …

The quantum anomalous Hall effect (QAHE) is a quantized Hall effect that occurs at zero
magnetic field. Its mechanism and properties are different from those of conventional …

Quantum Hall effect (QHE) not only reveals a new quantum state of matter but also can be
used for low‐power‐consumption high‐speed electronic devices because of the existence …

We report experimental investigations on the quantum phase transition between the two
opposite Hall plateaus of a quantum anomalous Hall insulator. We observe a well-defined …

Over a long period of exploration, the successful observation of quantized version of
anomalous Hall effect (AHE) in thin film of magnetically doped topological insulator (TI) …

The quantum Hall liquid is a novel state of matter with profound emergent properties such as
fractional charge and statistics. The existence of the quantum Hall effect requires breaking of …

We study the effect of disorder on the anomalous Hall effect (AHE) in two-dimensional
ferromagnets. The topological nature of the AHE leads to the integer quantum Hall effect …

The quantum anomalous Hall (QAH) effect in magnetic topological insulators is driven by the
combination of spontaneous magnetic moments and spin-orbit coupling. Its recent …

Abstract The Quantum Hall Effect (QHE) is one of the most remarkable condensed-matter
phenomena discovered in the second half of the 20 th century. It rivals superconductivity in …

The Hall effects comprise one of the oldest but most vital fields in condensed matter physics,
and they persistently inspire new findings, such as quantum Hall effects and topological …
