WebbThe spin-Seebeck effect together with a high spin thermoelectric conversion efficiency has been regarded as one of the core topics in spin caloritronics. ... eight-membered rings to investigate the thermal spin currents and thermoelectric properties by using density functional theory combined with the non-equilibrium Green's function method. WebbSpin Seebeck effect In 2008, physicists discovered the Spin Seebeck effect (SSE). This effect refers to the generation of a spin voltage caused by a temperature gradient in a ferromagnet. This gradient enables the thermal injection of spin currents from the ferromagnet into a nonmagnetic metal.
Webb5 apr. 2024 · Here we present a theory for the diffusive magnonic spin current generated in a magnetic insulator layer by a thermal gradient in the spin Seebeck effect. We show that the formulations describing magnonic perturbation using a position-dependent chemical potential and those using a magnon accumulation are completely equivalent.
Webb26 juni 2024 · The longitudinal spin Seebeck effect (LSSE) consists in the generation of a spin current parallel to a temperature gradient in a magnetic material. The LSSE has only been measured unequivocally in magnetic insulators because in metallic films it is contaminated by the anomalous Nernst effect (ANE).
