Anomalous Hall effect in ZrTe5 [PDF]

open access: yesNature Physics, 2018
ZrTe$_5$ has been of recent interest as a potential Dirac/Weyl semimetal material. Here, we report the results of experiments performed via in-situ 3D double-axis rotation to extract the full $4 $ solid angular dependence of the transport properties. A clear anomalous Hall effect (AHE) was detected for every sample, with no magnetic ordering observed ...

Symmetry-protected difference between spin Hall and anomalous Hall effects of a periodically driven multiorbital metal

open access: yesCommunications Physics, 2023
Nonequilibrium quantum states can be controlled via the driving field in periodically driven systems. Such control, which is called Floquet engineering, has opened various phenomena, such as the light-induced anomalous Hall effect.

Anomalous Hall Effect in Ferromagnetic Semiconductors [PDF]

open access: yesPhysical Review Letters, 2002
We present a theory of the anomalous Hall effect in ferromagnetic (Mn,III)V semiconductors. Our theory relates the anomalous Hall conductance of a homogeneous ferromagnet to the Berry phase acquired by a quasiparticle wavefunction upon traversing closed paths on the spin-split Fermi surface of a ferromagnetic state.

Photonic Anomalous Quantum Hall Effect

open access: yesPhysical Review Letters, 2019
We experimentally realize a photonic analogue of the anomalous quantum Hall insulator using a two-dimensional (2D) array of coupled ring resonators. Similar to the Haldane model, our 2D array is translation invariant, has zero net gauge flux threading the lattice, and exploits next-nearest neighbor couplings to achieve a topologically non-trivial ...

Giant magneto-optical responses in magnetic Weyl semimetal Co3Sn2S2

open access: yesNature Communications, 2020
The evidence of topological origin for the recently observed anomalous Hall effect remains elusive. Here, the authors report that the resonance of the optical Hall conductivity resulted from topological electronic structure gives rise to the large ...

Spin-neutral tunneling anomalous Hall effect

open access: yesPhysical Review B, 2022
Anomalous Hall effect (AHE) is a fundamental spin-dependent transport property that is widely used in spintronics. It is generally expected that currents carrying net spin polarization are required to drive the AHE. Here we demonstrate that, in contrast to this common expectation, a spin-neutral tunneling AHE (TAHE), i.e.
