Research Abstract
In this study, we performed thermal spin injection into organic materials and conducted experiments on the generation and detection of spin-polarized currents in organic materials. An organic spin Seebeck device with a crossbar structure was fabricated by using amorphous CoFeAl as a ferromagnetic layer, carbon as an organic conduction layer, and Pt as a spin current conversion layer. Pt has a large inverse spin Hall effect and is suitable as a spin current conversion layer. In the CoFeAl/carbon/Pt crossbar, the thermal spin current injection effect from the CoFeAl layer was observed by the Pt spin current conversion. Temperature dependence measurements were also performed. As future work, contribution and separation of the Nernst effect of the CoFeAl layer are necessary.
