Pressure tuning of intrinsic and extrinsic sources to the anomalous Hall effect in CrGeTe_{3}

Physical Review Research
The integrated Berry curvature is a geometric property that has dramatic implications for material properties. This study investigates the integrated Berry curvature and other contributions to the anomalous Hall effect in CrGeTe_{3} as a function of ...

The Anomalous Hall Effect

This article reviews the main contributions to the anomalous Hall effect and its resurgence in the past three decades, which has been accompanied by the rise of topological phenomena and topological materials. I will show that the anomalous Hall effect stems from the interplay of magnetism, spin-orbit coupling, disorder scattering and driving electric ...

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Gulf Stream ocean variability plays a key role in modulating atmospheric river (AR) activity over the North Atlantic during winter and spring at monthly time‐scales. Increased ocean heat transport and mesoscale activity in the Gulf Stream are linked to northward shifts in ARs, while stronger surface heat fluxes drive ARs southward.

Large anomalous Hall conductivity induced by spin chirality fluctuation in an ultraclean frustrated antiferromagnet PdCrO2

Communications Physics
Magnetic frustration, realized in the special geometrical arrangement of localized spins, often promotes topologically nontrivial spin textures in the real space and induces significantly large unconventional Hall responses.

Dirac fermions and topological phases in magnetic topological insulator films

SciPost Physics
We develop a Dirac fermion theory for topological phases in magnetic topological insulator films. The theory is based on exact solutions of the energies and the wave functions for an effective model of the three-dimensional topological insulator (TI ...

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

Advanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Tailoring the Anomalous Hall Effect in van der Waals Ferromagnet Fe3GeTe2

Taiyuan Ligong Daxue xuebao
[Purposes] The intrinsic magnetic moments of magnetic materials can lead to anomalous Hall effects, and the Hall resistance can be significantly reduced, thus improving the heat loss in micro- and nanoelectronic devices.
