Abstract We fabricated Fe3O4 nanoparticle (NP)-assembled films on flexible polyimide sheets with Pt or Ta cap layer using a spin coating method and DC sputtering.The films were elaborated for spin Seebeck thermoelectric generator applications, and their spin Seebeck voltages were observed.We showed that the thermoelectric power of [Pt film/Fe3O4 NP] n multilayered films increases with increasing number of stacking n.

Additionally, Shoe Scrapers we prepared spin Seebeck thermopile devices in which the Fe3O4 NP-assembled films capped by Pt and Ta are connected alternately in series.We demonstrated that spin Seebeck voltages of the thermopile devices are larger than those of single [Pt or Ta film/Fe3O4 NP] n piece.Our results indicate that the spin Seebeck thermoelectric power of Fe3O4 NPs can be BROWN CREAM enhanced using a simple fabrication process without lithography technique.
