Tunable anomalous Hall and Nernst effects in MM′X compounds [PDF]
Journal of Physics: Condensed Matter, 2022 Abstract Based on first-principles calculations, the anomalous Hall conductivity (AHC) and anomalous Nernst conductivities (ANCs) of the XMnP (X = Ti, Zr, Hf) compounds are evaluated, and the possibility to tailor such properties in compounds susceptible to changing the magnetization directions is also investigated.

Scattering-independent anomalous Nernst effect in ferromagnets [PDF]
Physical Review B, 2013 Using the full-potential linearized augmented plane-wave method within the density functional theory, we compute all contributions to the scattering independent part of the thermoelectric conductivity tensor, namely the intrinsic contribution and the side-jump contribution.

Anomalous spin Nernst effect in Weyl semimetals [PDF]
Journal of Physics: Condensed Matter, 2019 Abstract The spin Nernst effect describes a transverse spin current induced by the longitudinal thermal gradient in a system with the spin–orbit coupling. Here we study the spin Nernst effect in a mesoscopic four-terminal cross-bar Weyl semimetal device under a perpendicular magnetic field.

Large anomalous Nernst effect in the ferromagnetic Fe3Si polycrystal
The high-throughput calculation predicts that the Fe-based cubic ferromagnet Fe$_3$Si may exhibit a large anomalous Nernst effect (ANE). Here, we report our experimental observation of the large Nernst coefficient $S_{yx}\sim$2 $\mu$V/K and the ...

Anomalous Nernst effect in La0.5Ca0.5Coo3
, 2022 We report the occurrence of the anomalous Nernst effect (ANE) in polycrystalline perovskite La0.5Ca0.5CoO3. The sample is ferromagnetic below TC = 147 K and resistivity shows non-metallic behavior above and below the TC with only a small negative magnetoresistance (~2%) around TC.

Fluctuational anomalous Hall and Nernst effects in superconductors
Annals of Physics, 2020 In this work we develop microscopic kinetic theory of the anomalous Hall and Nernst effects in superconductors induced by fluctuations in the vicinity of the critical transition temperature. The technical analysis is carried out within the Matsubara diagrammatic technique and linear response Kubo formula with disorder averaging and an analytical ...

Exchange-biased topological transverse thermoelectric effects in a Kagome ferrimagnet
Nature Communications, 2022 Kagome metal TbMn6Sn6 was recently discovered to be a ferrimagnetic topological Dirac material. Here, the authors observe anomalous Nernst effect and anomalous thermal Hall effect which exhibit asymmetry with respect to the magnetic field.
