Field-linear anomalous Hall effect and Berry curvature induced by spin chirality in the kagome antiferromagnet Mn3Sn [PDF]

Nature Communications, 2023
Berry curvature sits at the heart of both the anomalous hall effect and topological hall effect, with the former arising from a momentum space berry curvature, while the latter arises from a real space berry curvature.

Large intrinsic anomalous Hall effect in SrIrO3 induced by magnetic proximity effect [PDF]

Nature Communications, 2021
The anomalous Hall effect (AHE) occurs in ferromagnets caused by intrinsic and extrinsic mechanisms. Here, Yoo et al. report large anomalous Hall conductivity and Hall angle at the interface between a ferromagnet La0.7Sr0.3MnO3 and a semimetallic SrIrO3,

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

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 ...

Towards the quantized anomalous Hall effect in AlOx-capped MnBi2Te4 [PDF]

Nature Communications
The quantum anomalous Hall effect in layered antiferromagnet MnBi2Te4 harbors a rich interplay between magnetism and topology, holding a significant promise for low-power electronic devices and topological antiferromagnetic spintronics.

Study on Anomalous Hall Effect and Spin–Orbit Torque Effect of TbCo-Based Multilayer Films [PDF]

Nanomaterials
The anomalous Hall effect and spin–orbit torque of TbCo-based multilayer films have been methodically studied in recent years. Many properties of the films can be obtained by the anomalous Hall resistance loops of the samples. We report on the effects of

Extrinsic anomalous Hall effect in van der Waals ferromagnet Fe5GeTe2

AIP Advances, 2023
We investigate the anomalous Hall effect in a van der Waals material Fe5GeTe2. We find a distinct difference in the temperature dependence of the anomalous Hall effect associated with the evolution of magnetic states in Fe5GeTe2 films.

Saturation of the anomalous Hall effect at high magnetic fields in altermagnetic RuO2

APL Materials, 2023
Observations of the anomalous Hall effect in RuO2 and MnTe have demonstrated unconventional time-reversal symmetry breaking in the electronic structure of a recently identified new class of compensated collinear magnets, dubbed altermagnets.

Electric field control of anomalous Hall effect in CaIrO3/CaMnO3 heterostructure

APL Materials, 2022
We demonstrate an electric field control of an anomalous Hall effect emerging in CaIrO3/CaMnO3 heterostructures. We fabricate both electron-type and hole-type carrier samples by tuning epitaxial strain and, then, control the carrier density in a CaIrO3 ...
