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

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.
