WebNov 25, 2024 · Introduction. Yttrium iron garnet (Y 3 Fe 5 O 12, YIG) is an insulating ferrimagnet with an extremely low Gilbert damping parameter in the order of 10 −4 1, 2 making it the ideal choice for spin transport studies, including inverse spin Hall effect (ISHE) 3, spin Seebeck effect 4, spin wave propagation 5, and spin colossal magnetoresistance … Webdependent effective damping α eff directly from the pinning linewidth, and even recover the intrinsic Gilbert damping at large applied fields. We therefore show that magneto-elastic coupling to SAWs is not detrimental, but rather provides an alternative path towards damping analysis in patterned arrays for a wide range of damping values.
