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

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 ...

Trans-scale spin Seebeck effect in nanostructured bulk composites based on magnetic insulator [PDF]

Nature Communications
The spin Seebeck effect enables thermoelectric conversion through thermally generated spin currents in magnetic materials, offering a promising transverse geometry for scalable devices. However, conventional spin Seebeck devices are confined to nanoscale

Origin of the spin Seebeck effect in compensated ferrimagnets [PDF]

Nature Communications, 2016
Ferrimagnets possess multiple spin sub-lattices resulting in a complex magnon band structure and subtle spin transport across interfaces. Here, the authors show how the spin Seebeck effect, the thermal generation of pure spin current, may be an effective

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 ...

Modulating the Spin Seebeck Effect in Co₂FeAl Heusler Alloy for Sensor Applications [PDF]

Sensors, 2020
The thermoelectric conversion technique has been explored in a broad range of heat-flow sensors. In this context, the Spin Seebeck Effect emerges as an attractive candidate for biosensor applications, not only for the sensibility improvement but also for

Spin Seebeck effect mediated reversal of vortex-Nernst effect in superconductor-ferromagnet bilayers [PDF]

Scientific Reports, 2023
We report on the observation of sign reversal of vortex-Nernst effect in epitaxial NbN/Fe bilayers deposited on MgO (001) substrates. Strong coupling between vortex magnetisation and ferromagnetic magnetisation at the NbN/Fe bilayer interface is ...

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

Nature 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.

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.
