TL;DR
This paper investigates the rapid temporal evolution of the spin Seebeck effect in YIG|Pt bilayers, revealing it occurs within sub-microsecond timescales and depends on thermal gradients and magnon diffusion.
Contribution
It introduces a thermal-driven magnon-diffusion model to explain the sub-microsecond dynamics of the spin Seebeck effect in YIG|Pt systems.
Findings
The spin Seebeck effect occurs within sub-microsecond timescales.
The effective thermal-magnon diffusion length is approximately 700nm.
The temporal behavior depends on the development of the temperature gradient near the interface.
Abstract
We present temporal evolution of the spin Seebeck effect in a YIG|Pt bilayer system. Our findings reveal that this effect is a sub-microseconds fast phenomenon governed by the temperature gradient and the thermal magnons diffusion in the magnetic materials. A comparison of experimental results with the thermal-driven magnon-diffusion model shows that the temporal behavior of this effect depends on the time development of the temperature gradient in the vicinity of the YIG|Pt interface. The effective thermal-magnon diffusion length for YIG|Pt systems is estimated to be around 700nm.
