Theory of the spin seebeck effect
WebbWe demonstrate that a spin-dependent Seebeck effect can be detected in quantum wells with zinc-blend structure with equal Rashba-Dresselhaus spin-orbit couplings. This theory is based on the ... 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.

WebbMagnetic field effects (MPE) of radical pair (RP) recombination in micelles are investigated both analytically and numerically. The confinement effect of a micelle is modeled by a spherically symmetric potential well. The results show that the contribution from ST_ transitions to all kind of MFEs is significantly increased due to the confinement effect. … trust trade philippines firearmsWebb9 juli 2013 · Abstract We theoretically investigate the longitudinal spin Seebeck effect, in which the spin current is injected from a ferromagnet into an attached nonmagnetic metal in a direction parallel to the temperature gradient. philips.be webshopWebb24 feb. 2024 · We present a theory of the nonlinear spin Seebeck effect (SSE) in a … trust traders bahrainWebb10 apr. 2024 · We report on the single-molecule electronic and thermoelectric properties of strategically chosen anthracene-based molecules with anchor groups capable of binding to noble metal substrates, such as gold and platinum.
