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

open access: yesNature 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

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

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

open access: yesSensors, 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

Seebeck effect in magnetic tunnel junctions [PDF]

open access: yesNature 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.

Large Seebeck effect by charge-mobility engineering. [PDF]

open access: yesNat Commun, 2015
AbstractThe Seebeck effect describes the generation of an electric potential in a conducting solid exposed to a temperature gradient. In most cases, it is dominated by an energy-dependent electronic density of states at the Fermi level, in line with the prevalent efforts towards superior thermoelectrics through the engineering of electronic structure ...

Magneto-Seebeck effect in bismuth

open access: yesPhysical 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.

Anemometer based on Seebeck effect

open access: yesSensors and Actuators A: Physical, 2003
This paper presents the realisation of anemometers based on periodic structures elaborated by flash evaporation technique on polyimide substrate using Bi2Te3-Sb2Te3(P) and Bi2Te3-Bi2Se3(N) materials which have a high figure of merit. These anemometers are based on both Seebeck and Joule effects.

Intrinsic nonlinear Nernst and Seebeck effect

open access: yesNew Journal of Physics
The Nernst and Seebeck effects are crucial for thermoelectric energy harvesting. However, the linear anomalous Nernst effect requires magnetic materials with intrinsically broken time-reversal symmetry.

Oxide Thermoelectric Energy Harvesting Materials [PDF]

open access: yes, 2014
Conventional thermoelectric materials found in many thermoelectric devices have unfavourable properties; they often suffer instability at high temperatures and contain toxic metals which pose a hazard to the environment.
