WebNov 7, 2016 · The Spin Hall Effect results in the aggration of spin (the spin directions at one edge of a current carrying conducting material being opposite to the other edge). In most cases the current carrying conductor will be a wire, upon the surface of which the spins will wind around the surface. Image Source: Wikipedia Spin Hall Effect WebAug 31, 2015 · The Rashba effect is very similar to the spin hall effect in the sense that it generates a spin-current. The main difference is that the Rashba effect happens at the interface between two different materials, while the spin hall effect happens in the bulk of a material. So, a multi-layer device can have bulk spin-currents and interface spin ...
