Anomalous Nernst effect beyond the magnetization scaling relation in the ferromagnetic Heusler compound Co2MnGa [PDF]

NPG Asia Materials, 2018
Applying a temperature gradient in a magnetic material generates a voltage that is perpendicular to both the heat flow and the magnetization. This phenomenon is the anomalous Nernst effect (ANE), which was long thought to be proportional to the value of ...

Large Anomalous Hall and Nernst Effects in High Curie‐Temperature Iron‐Based Heusler Compounds

Advanced Science, 2021
The interplay between topology and magnetism has recently sparked the frontier studies of magnetic topological materials that exhibit intriguing anomalous Hall and Nernst effects owning to the large intrinsic Berry curvature (BC).

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.

Nernst effect in poor conductors and the cuprate superconductors [PDF]

, 2004
We calculate the Nernst signal in disordered conductors with the chemical potential near the mobility edge. The Nernst effect originates from interference of itinerant and localised-carrier contributions to the thermomagnetic transport.

Nernst Effect in Electron-Doped Pr$_{2-x}$Ce$_{x}$CuO$_4$ [PDF]

, 2003
The Nernst effect of Pr$_{2-x}$Ce$_{x}$CuO$_4$ (x=0.13, 0.15, and 0.17) has been measured on thin film samples between 5-120 K and 0-14 T. In comparison to recent measurements on hole-doped cuprates that showed an anomalously large Nernst effect above ...

Sign change of anomalous Hall effect and anomalous Nernst effect in the Weyl semimetal CeAlSi [PDF]

Physical review B, 2022
We report the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) data for the non-collinear Weyl semimetal CeAlSi. The anomalous Hall conductivity ({\sigma}_ij^A) was measured for two different orientations of the magnetic field (B ...

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.

Comparative study on the thermoelectric effect of parent oxypnictides La$T$AsO ($T$ = Fe, Ni) [PDF]

, 2010
The thermopower and Nernst effect were investigated for undoped parent compounds LaFeAsO and LaNiAsO. Both thermopower and Nernst signal in iron-based LaFeAsO are significantly larger than those in nickel-based LaNiAsO.

Anomalous Nernst Effects of [CoSiB/Pt] Multilayer Films

Journal of Magnetics, 2013
We report a measurement for the anomalous Nernst effects induced by a temperature gradient in [CoSiB/Pt] multilayer films with perpendicular magnetic anisotropy. The Nernst voltage shows a characteristic hysteresis which reflects the magnetization of the film as in the case of the anomalous Hall effects.
