WebJun 15, 2024 · The source of it is expected to be magnon-electron interactions. Namely, we assume that the external voltage is applied to the “active” layer stimulating electric current through this layer. In its turn, the scattering of the current-carrying electrons by magnons leads to a magnon drag current within this layer. The 3-magnons interactions ... WebSep 13, 2024 · Here, we extend the observation of magnon drag in magnetically ordered materials to paramagnets in which the local thermal fluctuations of the magnetization (paramagnons) have a finite lifetime, τ L, and a spin-spin correlation length, ξ.We argue that when τ L ≫ τ me, the electron-on-magnon scattering time, and the spatial extent of the …

WebMagnon scattering platform and coherent sensing with a single spin magnetometer. (A) Sketch of the magnon-based scattering platform, comprising a microwave stripline as a source, a single NV on a scanned tip as a detector, 100-nm-thick YIG as the “vacuum” supporting long-lived propagating magnons, and a disk-shaped target.The single NV … WebDec 1, 1984 · Nevertheless the electron-magnon interaction is quasielastic i.e. the energy transferred from the electron to the magnons during the scattering event is much smaller than the electron energy. If a sufficiently strong electric field is applied to the semiconductor, the electrons are heated up and the electron temperature may considerably exceed ... roblox screech image id
