Influence of spin-orbit and spin-Hall effects on the spin Seebeck current beyond linear response

L. Chotorlishvili, Z. Toklikishvili, X. -G. Wang +3

We study the spin transport theoretically in heterostructures consisting of a ferromagnetic metallic thin film sandwiched between heavy-metal and oxide layers. The spin current in…

Strong Hot Carrier Effects Observed in a Single Nanowire Heterostructure

Iraj Abbasian Shojaei, Samuel Linser, Giriraj Jnawali +9

We use Transient Rayleigh Scattering to study the thermalization of hot photoexcited carriers in single GaAsSb/InP nanowire heterostructures. By comparing the energy loss rate in s…

Thermoelastic enhancement of the magnonic spin Seebeck effect in thin films and bulk samples

L. Chotorlishvili, X. -G. Wang, Z. Toklikishvili +1

A non-uniform temperature profile may generate a pure spin current in magnetic films, as observed for instance in the spin Seebeck effect. In addition, thermally induced elastic de…

Unique Spin Vortices in Quantum Dots with Spin-orbit Couplings

Wenchen Luo, Amin Naseri, Jesko Sirker +1

Spin textures of one or two electrons in a quantum dot with Rashba or Dresselhaus spin-orbit couplings reveal several intriguing properties. We show that even at the single-electro…
