We investigate the substrate annealing effect of thermoelectric voltage induced by the spin-Seebeck effect in Pt/polycrystalline yttrium iron garnet Y3Fe5O12(YIG) structures with different Pt thicknesses. The thermoelectric voltage is increased by decreasing the Pt thickness to 1.9nm as well as by annealing. Annealing at 1073K for 5 h enhances the thermoelectric voltage up to 7.4 μV/K in structures with 1.9 nm Pt thickness.
