Fig. 3

a Slice of the Fermi surface of a 2DEG with Rashba spin orbit coupling at a certain energy. The directions of the arrows indicate the spin alignment of the electron in the xy plane, and the colour of the bands indicates the spin of the electron measured along the x direction. b Classical trajectories of electrons injected into the scattering area of a TMF device with an out-of-plane magnetic field \(B_{{z}}\) applied. The colour of the lines indicates the x-component of the spin of the electron, blue indicates spin-down, red indicates spin-up and grey indicates zero spin in x. The solid line shows the path of electrons with spin-down in x at the injection point, and the dashed line shows the path of electrons with spin-up in x at the injection point. Circled numbers in both figures label corresponding positions in real space and k-space
