Generic Seebeck effect from spin entropy [PDF]

open access: yesThe Innovation, 2021
How magnetism affects the Seebeck effect is an important issue of wide concern in the thermoelectric community but remains elusive. Based on a thermodynamic analysis of spin degrees of freedom on varied d-electron-based ferromagnets and antiferromagnets,

Antiferromagnetic spin Seebeck Effect [PDF]

open access: yesPhysical 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.

Phonon driven spin distribution due to the spin-Seebeck effect

open access: yesPhysical Review Letters, 2011
Here we report on measurements of the spin-Seebeck effect of GaMnAs over an extended temperature range alongside the thermal conductivity, specific heat, magnetization, and thermoelectric power.

Room temperature and low-field resonant enhancement of spin Seebeck effect in partially compensated magnets [PDF]

open access: yesNature Communications, 2019
The spin Seebeck effect (SSE) converts thermally induced magnetization dynamics in magnetic materials to spin currents, but is so far an inefficient process.

First-principles investigation of spin-dependent thermoelectric transport and spin Seebeck in Fe(110)/Co( $$11\bar{2}0$$ ) heterostructures [PDF]

open access: yesScientific Reports
We compute spin-dependent thermoelectric properties of Fe(110)/Co( $$11\bar{2}0$$ ) thin films using spin-polarized density functional theory combined with semiclassical Boltzmann transport. The spin-resolved Seebeck coefficients $$S^{\uparrow }(T)$$ and

Cryogenic spin Seebeck effect [PDF]

open access: yesPhysical 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 ...

Modulation of spin Seebeck effect by hydrogenation [PDF]

open access: yesApplied Physics Letters, 2022
We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In the presence of 3% hydrogen gas, SSE voltage decreases by more than 50% from the magnitude observed in pure Ar gas. The modulation of the SSE voltage is reversible, but the recovery of the SSE voltage to the prehydrogenation value takes a few days because

Ab initio calculation of thermoelectric properties in 3d ferromagnets based on spin-dependent electron–phonon coupling

open access: yesNew Journal of Physics, 2023
Crossed magneto-thermo-electric coefficients are central to novel sensors and spin(calori)tronic devices. Within the framework of Boltzmann’s transport theory, we calculate the resistivity and Seebeck coefficients of the most common 3 d ferromagnetic ...

Theory of the spin Seebeck effect [PDF]

open access: yesReports on Progress in Physics, 2013
The spin Seebeck effect refers to the generation of a spin voltage caused by a temperature gradient in a ferromagnet, which enables the thermal injection of spin currents from the ferromagnet into an attached nonmagnetic metal over a macroscopic scale of several millimeters.
