More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook ...

A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated, validating a recent theoretical prediction.

Theorists have observed a rare phenomenon called the quantum anomalous Hall effect in a very simple material. Previous experiments have detected it only in complex or delicate materials. Theorists at ...

The quantum anomalous Hall effect (QAHE) has unique advantages in topotronic applications, but it is still a key scientific challenge to realize the QAHE with tunable magnetic and topological ...

The anomalous Hall effect displays non-monotonic temperature dependence and sign reversals, originating from the competition between short-range and long-range spin correlations and their ...

Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...
