Anomalous Hall Effect in Phase-Disordered Superconductors: A Theory Based on Screened Vortex Charge
The anomalous Hall conductivity in a phase-disordered superconductor above the BKT transition is determined by the high-frequency AC Hall conductivity, which is closely related to the normal state anomalous Hall conductivity and Fermi surface Berry phase, despite the screening of vortex charge by many-body interactions.
Pressure-Tuned Anomalous Hall Effect in CrGeTe3: Unveiling the Interplay of Intrinsic and Extrinsic Contributions
This study investigates the pressure-dependent behavior of the anomalous Hall effect (AHE) in CrGeTe3, revealing a complex interplay of intrinsic Berry curvature and extrinsic scattering mechanisms that can be tuned by pressure.
Regulation of the Extrinsic Contribution to the Anomalous Hall Effect in Fe-rich Kagome Magnet Fe3Sn
By increasing the iron content in the kagome magnet Fe3Sn, researchers successfully suppressed the extrinsic contribution to the anomalous Hall effect, leading to a dominant intrinsic contribution and a large anomalous Hall conductivity close to the theoretically predicted value.
Giant Anomalous Hall Effect from Domain Wall Skew Scattering in Layered Antiferromagnet EuAl2Si2
Giant anomalous Hall effect, originating from domain wall skew scattering, is observed in the layered antiferromagnet EuAl2Si2, opening new avenues for spintronics.
Ultrafast Anomalous Hall Current Generation and Detection in Bulk GaAs via Terahertz Emission: Influence of Landau Levels and Valence Band Contributions
This research paper investigates the generation of anomalous Hall currents (AHCs) in bulk GaAs under the influence of Landau levels, revealing discrete AHC enhancements at Landau transition energies, even at room temperature, attributed to the energy dependence of geometric phases and valence band contributions.
