Thermally driven anomalous Hall effect transitions in FeRh

, 2018
Materials exhibiting controllable magnetic phase transitions are currently in demand for many spintronics applications. Here, we investigate from first principles the electronic structure and intrinsic anomalous Hall, spin Hall, and anomalous Nernst ...

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

Advanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

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 ...

Amorphous Tungsten Driving Extraordinary Long‐Range Interlayer Exchange Coupling and Large Spin‐Orbit Torque

Advanced Electronic Materials, EarlyView.
The amorphous tungsten (W) is found to be a promising non‐magnetic interlayer simultaneously driving the long‐range interlayer exchange coupling and the large spin Hall effect in a synthetic antiferromagnet (SyAF). Thanks to these characteristics, efficient spin‐orbit torque switching is achieved in the SyAF.

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 ...

Coexistence of Large Nernst Effect and Axis‐Dependent Conduction Polarity in Semimetal MoSi2

Advanced Electronic Materials, EarlyView.
MoSi2${\rm MoSi}_2$ is a rare material in which axis‐dependent conduction polarity (ADCP) and a large ordinary Nernst effect (ONE) coexist. The pronounced ONE (199μVK−1$199\,\umu \mathrm {V}\,\mathrm {K}^{-1}$) originates from nearly perfect carrier compensation, high mobility, and likely phonon drag, while ADCP arises from mixed‐dimensionality of the ...

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.

Stable Magnetic Nanodomains Engineered Via Ga+‐ion Irradiation For Deterministic Sequential Switching

Advanced Electronic Materials, EarlyView.
Tiny magnetic regions separated by domain walls can store data, but controlling them precisely is difficult. We use focused ion beams to create nanoscale “anisotropy wells” that pin these walls from both sides. This bidirectional pinning holds domains stable in either direction, even with no field applied.
