Rashba-Effect and Intrinsic Spin Hall Effect

[JanSpintronics]

Hello everybody,

Im looking for a good explanation for the Rashba effect or Rashba Spin Orbit coupling (when it is the same effect with 2 names?) . If somebody can help me here that would be awesome. Moreover i try to understand the intrinsic mechanism of the Spin Hall Effect with the Berry Curvature, hopefully i figured it out that this has to do with the rashba effect. If somebody can give a nice explanation that would be awesome but i also looking for a good article in a book or paper where i can find it. I already know something about Sinova but... I really don't understand it...

Greetings

Spintronics isn't really my field, but I'll give it a shot. Both the Rashba effect and the spin Hall effect have their origins in spin-orbit coupling. For the Rashba effect, the presence of an electric field perpendicular to a 2D conductor causes the electrons to experience a magnetic field, which the electron spins interact with. This leads to a momentum dependence of the spin. For the spin Hall effect, current in a wire will induce a magnetic field around that wire. The electron spins will couple with that magnetic field and this coupling will cause opposite spins to move in different directions. That's about the extent of my knowledge on that topic.
