Anomalous Nernst Effect in Nonmagnetic Nodal Line Semimetal PbTaSe$_2$

, 2021
PbTaSe$_2$ is a unique topological material, in which the number of nodal lines is expected to change at the structural transition between the lower temperature/pressure "L" phase and the higher temperature/pressure "H" phase.

Enhanced anomalous Nernst effect in disordered Dirac and Weyl materials

, 2022
© 2021 American Physical Society. We analyze the thermoelectric response of Dirac and Weyl semimetals using the semiclassical approach, focusing on the extrinsic contributions due to skew-scattering and side jump. Our results apply to the linear response

Identifying the octupole antiferromagnetic domain orientation in Mn3NiN 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.

Crossover Behavior of the Anomalous Hall Effect and Anomalous Nernst Effect in Itinerant Ferromagnets [PDF]

Physical Review Letters, 2007
The anomalous Hall effect (AHE) and anomalous Nernst effect (ANE) are experimentally investigated in a variety of ferromagnetic metals including pure transition metals, oxides, and chalcogenides, whose resistivities range over 5 orders of magnitude. For these ferromagnets, the transverse conductivity sigma{xy} versus the longitudinal conductivity sigma{

Anomalous Nernst Effect-Based Near-Field Imaging of Magnetic Nanostructures. [PDF]

ACS Nano
The anomalous Nernst effect (ANE) gives rise to an electrical response transverse to magnetization and an applied temperature gradient in a magnetic metal. A nanoscale temperature gradient can be generated by the use of a laser beam applied to the apex of an atomic force microscope tip, thereby allowing for spatially resolved ANE measurements beyond ...

Emerging of Anomalous Higher-Order Topological Phases in Altermagnet/Topological Insulator Heterostructure by Floquet Engineering. [PDF]

Adv Sci (Weinh)
We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

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.

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 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 ...
