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 ...

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

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. Here, we demonstrate the observation of one important effect of this class: the magneto-Seebeck effect.

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

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. Using Pt as a spin detector layer it is possible to measure thermally generated spin current from MnF$_2$ through ...

Magneto-Seebeck effect in magnetic tunnel junctions with perpendicular anisotropy
AIP Advances, 2017 As one invigorated filed of spin caloritronics combining with spin, charge and heat current, the magneto-Seebeck effect has been experimentally and theoretically studied in spin tunneling thin films and nanostructures.

Magneto-Seebeck effect in bismuth
Physical Review B, 2022 Thermoelectricity was discovered almost two centuries ago in bismuth. The large and negative Seebeck coefficient of this semimetal remains almost flat between 300 K and 100 K. This striking feature can be understood by considering the ratio of electron and hole mobilities and the evolution of their equal densities with temperature.

Topology dependence of skyrmion Seebeck and skyrmion Nernst effect
Scientific Reports, 2022 We explore the dynamics of skyrmions with various topological charges induced by a temperature gradient in an ultra-thin insulating magnetic film. Combining atomistic spin simulations and analytical calculations we find a topology-dependent skyrmion ...
