- Abstract
Spin current and spin accumulation of a finite width quantum ring (QR) in the presence of a homogeneous perpendicular magnetic field and Rashba spin-orbit coupling have been investigated. A non-equilibrium Green's function (NEGF) approach has been followed in coherent regime. Numerical results show that spatial magnetization of the transport electrons oscillates throughout the QR and the spin current and spin accumulation can be controlled by the Rashba coupling, bias voltage, and magnetic field.
