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.
