Amplification of spin waves by the spin Seebeck effect

Journal of Applied Physics, 2012
We observe amplification of spin-wave packets propagating along a film of single-crystal yttrium iron garnet (YIG) subject to a transverse temperature gradient. The spin waves are excited and detected with standard techniques used to study volume or surface magnetostatic waves in the 1–2 GHz frequency range.

Numerical study on the spin Seebeck effect

Physical Review B, 2011
Thermally driven spin-wave spin current in a ferromagnetic material (FM) and the resulting electric signal in a normal metal (NM) probe placed on the FM are theoretically investigated by taking into account the fluctuation-dissipation theorem for thermally fluctuating spin at the interface of an FM-NM junction.

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.

Theory of the spin Seebeck effect in antiferromagnets

Physical Review B, 2016
The spin Seebeck effect (SSE) consists in the generation of a spin current by a temperature gradient applied in a magnetic film. The SSE is usually detected by an electric voltage generated in a metallic layer in contact with the magnetic film resulting from the conversion of the spin current into charge current by means of the inverse spin Hall effect.
