Webb24 feb. 2024 · We present a theory of the nonlinear spin Seebeck effect (SSE) in a ferromagnetic nanowire at cryogenic temperatures. We adopt a microscopic quantum noise model based on a collection of two-level systems. At certain positions of Pt detectors to the wire, the transverse SSE changes sign as a function of temperature and/or …
Webb1 juli 2024 · To clearly show how SSE occurs in BMS, we study the thermal spin transport (TST) characters of magnetic MoS 2 nanotube (NT) using first-principles density function theory (DFT) and non-equilibrium Green’s function (NEGF) methods. Controlling synthesis of MoS 2 NT is already a proven technique [9], and various field-effect transistors based … WebbThe spin Seebeck effect (SSE) refers to the generation of a spin voltage caused by a temperature gradient in a ferromagnet, which enables the thermal injection of spin currents from the ferromagnet into an attached nonmagnetic metal over a macroscopic scale of several millimeters.
