Scalar spin chirality Nernst effect

Physical Review Research
The scalar spin chirality, which characterizes the fundamental unit of noncoplanar spin structures, plays an important role in rich chiral physics of magnetic materials.

Intrinsic nonlinear Nernst and Seebeck effect

New Journal of Physics
The Nernst and Seebeck effects are crucial for thermoelectric energy harvesting. However, the linear anomalous Nernst effect requires magnetic materials with intrinsically broken time-reversal symmetry.

Thermal spin transport phenomena and their correlation to magnetic properties of metallic Pt/Co1-xFex and Pt/Ni1-xFex bilayers [PDF]

Science and Technology of Advanced Materials
We investigate the thermal spin transport phenomena in ferromagnetic metals with an adjacent spin-polarized Pt layer examining sputter-deposited Pt/Co1-xFex and Pt/Ni1-xFex bilayers.

Observation of anomalously large Nernst effects in conducting polymers [PDF]

Nature Communications
As a fundamental thermoelectric phenomenon in many solid-state materials, the Nernst effect has yet to be observed in conducting polymers. This knowledge could provide important insight into their elusive mechanism, which are crucial for flexible ...

Magnon orbital Nernst effect in altermagnets

npj Quantum Materials
Rotating magnon wave packets carrying orbital moments offer a pathway to unconventional transport phenomena. Here, we investigate magnon orbital moments and the magnon orbital Nernst effect in the prototypical altermagnets RuO2 and CrSb using first ...

Nonlinear magnon spin Nernst effect in antiferromagnets and strain-tunable pure spin current

Physical Review Research, 2022
In this paper, we study the spin Nernst effect of magnons in the nonlinear response regime. We derive the formula for the nonlinear magnon spin Nernst current by solving the Boltzmann equation and find out that it is described by an extended Berry ...

The Interplay of Magnetism and Thermoelectricity: A Review

Advanced Physics Research, 2023
The introduction of magnetism into a solid material might significantly modulate its electronic transport behavior, thereby serving as a means to tune the thermoelectric properties that have attracted considerable research attention in recent years.

Theory of Dissipationless Nernst Effects [PDF]

Physical Review Letters, 2010
We develop a theory of transverse thermoelectric (Peltier) conductivity, _{xy}, in finite magnetic field -- this particular conductivity is often the most important contribution to the Nernst thermopower. We demonstrate that _{xy} of a free electron gas can be expressed purely and exactly as the entropy per carrier irrespective of temperature ...

Spin Nernst effect and Nernst effect in two-dimensional electron systems [PDF]

Physical Review B, 2008
We study the Nernst effect and the spin Nernst effect, that a longitudinal thermal gradient induces a transverse voltage and a spin current. A mesoscopic four-terminal cross-bar device having the Rashba spin-orbit interaction (SOI) under a perpendicular magnetic field is considered.

Anomalous Nernst effect in perpendicularly magnetized τ-MnAl thin films

AIP Advances, 2023
τ-MnAl is interesting for spintronic applications as a ferromagnet with perpendicular magnetic anisotropy due to its high uniaxial magnetocrystalline anisotropy. Here, we report on the anomalous Nernst effect of sputter deposited τ-MnAl thin films.
