Evidence for the role of the magnon energy relaxation length in the Spin Seebeck Effect

Arati Prakash, Benedetta Flebus, Jack Brangham +3

Temperature-dependent spin-Seebeck effect data on Pt|YIG (Y${}_3$Fe${}_5$O${}_{12}$)|GGG (Gd${}_3$Ga${}_5$O${}_{12}$) are reported for YIG films of various thicknesses. The effect is reported…
