Antiferromagnetic spin Seebeck Effect [PDF]

Physical Review Letters, 2016
We report on the observation of the spin Seebeck effect in antiferromagnetic MnF$_2$. A device scale on-chip heater is deposited on a bilayer of Pt (4 nm)/MnF$_2$ (110) (30 nm) grown by molecular beam epitaxy on a MgF$_2$ (110) substrate.

Seebeck Effect in Nanoscale Ferromagnets [PDF]

Journal of Physics: Condensed Matter, 2017
We present a theory of the Seebeck effect in nanoscale ferromagnets with dimensions smaller than the spin diffusion length. The spin accumulation generated by a temperature gradient strongly affects the thermopower.

Seebeck Effect in Magnetic Tunnel Junctions [PDF]

Nature Materials, 2011
Creating temperature gradients in magnetic nanostructures has resulted in a new research direction, i.e., the combination of magneto- and thermoelectric effects.

Magneto-Seebeck effect in spin-valve with in-plane thermal gradient

AIP Advances, 2014
We present measurements of magneto-Seebeck effect on a spin valve with in-plane thermal gradient. We measured open circuit voltage and short circuit current by applying a temperature gradient across a spin valve stack, where one of the ferromagnetic ...

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.

Charged Colloids at the Metal–Electrolyte Interface

Colloids and Interfaces, 2022
We discuss the peculiarities of the structure of the interface between a metal and a stable colloidal dispersion of charged nanoparticles in an electrolyte. It is demonstrated that a quasi-2D ionic structure of elevated density arises in its vicinity due

Determination of Seebeck coefficient originating from phonon-drag effect using Si single crystals at different carrier densities

Scientific Reports, 2023
The phonon-drag effect is useful for improving the thermoelectric performance, especially the Seebeck coefficient. Therefore, the phonon and electron transport properties of Si single crystals at different carrier densities were investigated, and the ...

Cryogenic spin Seebeck effect [PDF]

Physical Review B, 2021
We present a theory of the non-linearities of the spin Seebeck effect (SSE) in a ferromagnetic nanowire at cryogenic temperatures. We adopt a microscopic quantum noise model based on a collection of two-level systems. At certain positions of Pt detectors to the wire, the transverse SSE changes sign as a function of temperature and/or temperature ...

Seebeck Effect of Dirac Electrons

Journal of the Physical Society of Japan, 2022
We study the Seebeck effect in the three-dimensional Dirac electron system based on the linear response theory with Luttinger's gravitational potential. The Seebeck coefficient $S$ is defined by $S = L_{12} / L_{11} T$, where $T$ is the temperature, and $L_{11}$ and $L_{12}$ are the longitudinal response coefficients of the charge current to the ...
