Generic Seebeck effect from spin entropy [PDF]
The 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,

Observation of nuclear-spin Seebeck effect [PDF]
Nature Communications, 2021 Thermoelectric effects are limited to electrons to occur, and disappear at low temperatures due to electronic entropy quenching. Here, the authors report thermoelectric generation caused by nuclear spins down to 100 mK due to nuclear-spin excitation in a

Magnetic Contribution to the Seebeck Effect [PDF]
Entropy, 2018 The Seebeck effect is derived within the thermodynamics of irreversible processes when the generalized forces contain the magnetic term M ∇ B . This term appears in the formalism when the magnetic field is treated as a state variable.

Spin Seebeck effect of correlated magnetic molecules [PDF]
Scientific Reports, 2021 In this paper we investigate the spin-resolved thermoelectric properties of strongly correlated molecular junctions in the linear response regime. The magnetic molecule is modeled by a single orbital level to which the molecular core spin is attached by ...

Abnormal Seebeck Effect in Vertically Stacked 2D/2D PtSe2/PtSe2 Homostructure [PDF]
Advanced Science, 2022 When a thermoelectric (TE) material is deposited with a secondary TE material, the total Seebeck coefficient of the stacked layer is generally represented by a parallel conductor model.

Two-Stage Seebeck Effect in Charged Colloidal Suspensions [PDF]
Entropy, 2021 We discuss the peculiarities of the Seebeck effect in stabilized electrolytes containing the colloidal particles. Its unusual feature is the two stage character, with the linear increase of differential thermopower as the function of colloidal particles ...

Variable Range Hopping Model Based on Gaussian Disordered Organic Semiconductor for Seebeck Effect in Thermoelectric Device [PDF]
Micromachines, 2022 We investigate the carrier concentration dependent Seebeck coefficient in Gaussian disordered organic semiconductors (GD-OSs) for thermoelectric device applications. Based on the variable-range hopping (VRH) theory, a general model predicting the Seebeck

Enhanced spin Seebeck effect via oxygen manipulation [PDF]
Nature Communications, 2023 Spin Seebeck effect (SSE) refers to the generation of an electric voltage transverse to a temperature gradient via a magnon current. SSE offers the potential for efficient thermoelectric devices because the transverse geometry of SSE enables to utilize ...
