TLDR
Inverse spin Hall effect (ISHE) detection of propagating spin waves using Pt. as discussed by the authors has been shown to correlate well with the increase of the Gilbert damping when decreasing thickness of YIG.Abstract:
High quality nanometer-thick (20 nm, 7 nm and 4 nm) epitaxial YIG films have been grown on GGG substrates using pulsed laser deposition. The Gilbert damping coefficient for the 20 nm thick films is 2.3 x 10-4 which is the lowest value reported for sub-micrometric thick films. We demonstrate Inverse spin Hall effect (ISHE) detection of propagating spin waves using Pt. The amplitude and the lineshape of the ISHE voltage correlate well to the increase of the Gilbert damping when decreasing thickness of YIG. Spin Hall effect based loss-compensation experiments have been conducted but no change in the magnetization dynamics could be detected.read more

Investigation of the unidirectional spin heat conveyer effect in a 200 nm thin Yttrium Iron Garnet film.
TL;DR: Comparison of Damon-Eshbach and backward volume modes shows that the unidirectional heat flow is indeed due to non-reciprocal spin-waves and this effect is of extreme importance when measuring the inverse spin-Hall effect.

TL;DR: In this paper, the authors investigated the spin dynamics in superconducting thin films via spin pumping from an adjacent insulating ferromagnet GdN film and showed that a profound coherence peak of the Gilbert damping was observed slightly below the critical temperature of the NbN, which agrees well with recent theoretical prediction for $s$-wave SCs in the presence of impurity spinorbit scattering.

Pure spin currents in magnetically ordered insulator/normal metal heterostructures
TL;DR: In this paper, the authors focus on four different manifestations of pure spin currents in such heterostructures: the spin pumping effect, the longitudinal spin Seebeck effect, spin Hall magnetoresistance and the allelectrical detection of magnon transport in nonlocal device concepts.

Spin Hall Effect
TL;DR: In this paper, it is proposed that when a charge current circulates in a paramagnetic metal, a transverse spin imbalance will be generated, giving rise to a spin Hall voltage, in the absence of charge current and magnetic field.

Conversion of spin current into charge current at room temperature: Inverse spin-Hall effect
TL;DR: In this article, a pure spin current was injected into a Pt thin film using spin pumping, and it was observed to generate electromotive force transverse to the spin current, consistent with the spin-Hall effect.

TL;DR: It is shown that a spin wave in an insulator can be generated and detected using spin-Hall effects, which enable the direct conversion of an electric signal into aspin wave, and its subsequent transmission through (and recovery from) an insulators over macroscopic distances.
