Chiral-phonon-activated spin Seebeck effect

Nature Materials, 2023
Utilization of the interaction between spin and heat currents is the central focus of the field of spin caloritronics. Chiral phonons possessing angular momentum arising from the broken symmetry of a non-magnetic material create the potential for generating spin currents at room temperature in response to a thermal gradient, precluding the need for a ...

Paramagnetic Spin Seebeck Effect

Physical Review Letters, 2015
We report the observation of the longitudinal spin Seebeck effect in paramagnetic insulators. By using a microscale on-chip local heater, we generate a large thermal gradient confined to the chip surface without a large increase in the total sample temperature. Using this technique at low temperatures (

Observation of the spin Seebeck effect

Nature, 2008
The generation of electric voltage by placing a conductor in a temperature gradient is called the Seebeck effect. Its efficiency is represented by the Seebeck coefficient, S, which is defined as the ratio of the generated electric voltage to the temperature difference, and is determined by the scattering rate and the density of the conduction electrons.

Spin seebeck and spin-dependent seebeck effect in ferromagnetic thin films

2016 IEEE International Nanoelectronics Conference (INEC), 2016
Spin caloritronics, aiming to recycle exponentially growing wasted thermal energy in nowadays nanoelectronics, has gradually evolved as a main branch of spintronics. Among different thermo-magneto-transport phenomena, spin Seebeck effect and spin dependent Seebeck effect are most attractive due to their capabilities to generate pure spin current and ...

Spin Seebeck effect

2017
Chapter 18 This chapter discusses the spin Seebeck effect (SSE), which stands for the generation of a spin current, a flow of spinangular momentum, as a result of a temperature gradient in magnetic materials. In spintronics and spin caloritronics, the SSE is of crucial importance because it enables simple and versatile generation of a spin current from

Spin Waves, Spin Currents and Spin Seebeck Effect

2012
The spin Seebeck effect is now established as a universal aspect of ferromagnets that enables thermal injection of spin currents from a ferromagnet into attached nonmagnetic metals over macroscopic scale of several millimeters. We show that the spin-wave degrees of freedom play a crucial role in the spin Seebeck effect.

Magneto-Seebeck effect in spin valves

Journal of Applied Physics, 2017
The magneto-Seebeck (MS) effect, which is also called magneto-thermo-power, was observed in Co/Cu/Co and NiFe/Cu/Co spin valves. Their Seebeck coefficients in the parallel state were larger than those in the antiparallel state, and the MS ratio defined as (SAP -SP)/SP could reach –9% in our case.
