Two-channel anomalous Hall effect in SrRuO3 [PDF]

, 2020
The Hall effect in SrRuO3 thin films near the thickness limit for ferromagnetism shows an extra peak in addition to the ordinary and anomalous Hall effects. This extra peak has been attributed to a topological Hall effect due to two-dimensional skyrmions

Giant magneto-optical responses in magnetic Weyl semimetal Co3Sn2S2

Nature 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 ...

Magnetotransport induced by anomalous Hall effect

, 2023
In a magnetic metal, the Hall resistance is generally taken to be the sum of the ordinary Hall resistance and the anomalous Hall resistance. Here it is shown that this empirical relation is no longer valid when either the ordinary Hall angle or the ...

Proper Scaling of the Anomalous Hall Effect [PDF]

Physical Review Letters, 2009
Working with epitaxial films of Fe, we succeeded in independent control of different scattering processes in the anomalous Hall effect. The result appropriately accounted for the role of phonons, thereby clearly exposing the fundamental flaws of the standard plot of the anomalous Hall resistivity versus longitudinal resistivity.

Photoinduced anomalous supercurrent Hall effect

Physical Review B, 2023
We predict a photoinduced Hall effect in an isotropic conventional two-dimensional superconductor with a built-in supercurrent exposed to a circularly-polarized light. This second-order with respect to the electromagnetic field amplitude effect occurs when the frequency of the field exceeds the double value of the superconducting gap. It reveals itself

Photonic Anomalous Quantum Hall Effect

Physical 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 ...

Multivariable Scaling for the Anomalous Hall Effect [PDF]

Physical Review Letters, 2015
We derive a general scaling relation for the anomalous Hall effect in ferromagnetic metals involving multiple competing scattering mechanisms, described by a quadratic hypersurface in the space spanned by the partial resistivities. We also present experimental findings, which show strong deviation from previously found scaling forms when different ...

Ambi-polar anomalous Nernst effect in a magnetic topological insulator

New Journal of Physics, 2017
We report electromagnetic and thermomagnetic transport studies on a magnetic topological insulator thin film Cr _0.15 (Bi _0.1 Sb _0.9 ) _1.85 Te _3 grown by molecular beam epitaxy. The temperature and gate voltage dependence of the anomalous Hall effect

Giant c-axis nonlinear anomalous Hall effect in Td-MoTe2 and WTe2

Nature Communications, 2021
Certain materials without inversion symmetry may allow for a nonlinear anomalous Hall effect with conserved time reversal symmetry. Here, the authors report an extremely large c-axis nonlinear anomalous Hall effect in the non-centrosymmetric Td phase of ...
