Large intrinsic anomalous Hall effect in SrIrO3 induced by magnetic proximity effect

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 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 ...

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 ...

Transport Properties in Magnetized Compact Stars

Particles, 2021
Transport properties of dense quark matter are discussed in the strong magnetic field, B. B dependence as well as density dependence of the Hall conductivity is discussed, based on the microscopic Kubo formula. We took into account the possibility of the

Transition from Anomalous Hall Effect to Topological Hall Effect in Hexagonal Non-Collinear Magnet Mn3Ga

Scientific Reports, 2017
We report experimental observation of large anomalous Hall effect exhibited in non-collinear triangular antiferromagnet D019-type Mn3Ga with coplanar spin structure at temperatures higher than 100 K. The value of anomalous Hall resistivity increases with

Exchange biased anomalous Hall effect driven by frustration in a magnetic kagome lattice

Nature Communications, 2020
The Weyl semimetal Co$$_{3}$$ 3 Sn$$_{2}$$ 2 S$$_{2}$$ 2 exhibits a combination of magnetic ordering with a large anomalous Hall effect. Lachman et al. find an intrinsic exchange bias of this anomalous Hall effect and attribute it to the coexistence of ...

Progress and prospects in the quantum anomalous Hall effect

APL Materials, 2022
The quantum anomalous Hall effect refers to the quantization of the Hall effect in the absence of an applied magnetic field. The quantum anomalous Hall effect is of topological nature and well suited for field-free resistance metrology and low-power ...
