Anomalous Nernst effect in epitaxially grown Fe4−xNixN films

AIP Advances, 2023
Anomalous Nernst effect of epitaxial Fe4−xNixN films on MgAl2O4(001) substrates was characterized. The Ni/Fe ratio (x) in Fe4−xNixN films was changed in the range of 0 ≤ x ≤ 2.8, and the Fe4−xNixN phase started to decompose into FeNi at about x = 2.2 ...

Anomalous Nernst-Ettingshausen effect in diluted magnetic semiconductors [PDF]

Journal of Physics: Conference Series, 2020
Abstract The magnetic field dependences of the Hall and Nernst-Ettingshausen effects in (In, Fe)Sb, (Ga, Fe)Sb, (Ga, Mn)As diluted magnetic semiconductors were investigated. The samples were fabricated on a semi-insulating GaAs substrates by pulsed laser deposition in vacuum. The manifestation of the anomalous Nernst-Ettingshausen effect

First-principles study of anomalous Nernst effect in half-metallic iron dichloride monolayer

APL Materials, 2020
We performed first-principles simulations to elucidate the transverse thermoelectric effect (anomalous Nernst effect) of the half-metallic FeCl2 monolayer. We analyzed its thermoelectricity based on the semiclassical transport theory including the effect

Anomalous Hall and Nernst Effects in FeRh

, 2020
Antiferromagnets with tunable phase transitions are promising for future spintronics applications. We investigated spin-dependent transport properties of FeRh thin films, which show a temperature driven antiferromagnetic-to-ferromagnetic phase transition.

Anomalous magnon Nernst effect of topological magnonic materials [PDF]

Journal of Physics D: Applied Physics, 2018
The magnon transport driven by thermal gradient in a perpendicularly magnetized honeycomb lattice is studied. The system with the nearest-neighbor pseudodipolar interaction and the next-nearest-neighbor Dzyaloshinskii-Moriya interaction (DMI) has various topologically nontrivial phases.

Large anomalous Nernst effect in a van der Waals ferromagnet Fe3GeTe2. [PDF]

Nano letters (Print), 2019
Anomalous Nernst effect, a result of charge current driven by temperature gradient, provides a probe of the topological nature of materials due to its sensitivity to the Berry curvature near the Fermi level. Fe3GeTe2, one important member of the recently

Identifying the octupole Antiferromagnetic domain orientation in Mn$_{3}$NiN by scanning Anomalous Nernst Effect microscopy [PDF]

, 2022
The intrinsic anomalous Nernst effect in a magnetic material is governed by the Berry curvature at the Fermi energy and can be realized in non-collinear antiferromagnets with vanishing magnetization.

Temperature dependence of the anomalous Nernst coefficient for Ni80Fe20 determined with metallic nonlocal spin valves

AIP Advances, 2020
The anomalous Nernst effect, which generates an out-of-plane charge voltage in response to a thermal gradient perpendicular to the magnetization of a ferromagnet, can play a significant role in many spintronic devices where large thermal gradients exist.
