Description

The Anomalous Hall effect (AHE) is a transport phenomenon in ferromagnets, which exhibit currents even in the absence of a magnetic field. Their inner magnetization breaks Time Reversal Symmetry, allowing the Berry Curvature (BC) to be finite. As a result, topological features close to the Fermi energy have a deep impact in the transport properties, leading to huge Anomalous Hall Conductivities (AHC). This has been a well-stablished paradigm for the last years for the linear AHC.
However, some recent experimental results might be pointing to something beyond it.
