Spin currents. Another well-known approach to creating a spin cur-rent emerges when an SO-dependent scattering potential interacts with electrons. This scattering potential can be caused by a strong electric field [6]. The effective spin-orbit coupling generated is called the Rashba spin-orbit (RSO) interaction. Recent experiments predict that. 2.2. Spin current in the Rashba spin orbital coupling model Let us now consider the particular case of the Rashba Hamiltonian in an external electric eld.

Manipulating the electron spin with the aid of spin-orbit coupling (SOC) is an indispensable element of spintronics. Electrostatically gating a material with strong SOC results in an effective magnetic field which can in turn be used to govern the electron spin.
