Experiment of spin-polarized transverse magnetic focusing and Monte Carlo simulation. (a) Collector voltage Vc as a function of out-of-plane magnetic field Bop for different quantized channel conditions. (Ne, Nc) denotes quantized conductance in units of 2e2/h as (0.5, 0.5) as red, (0.5, 1.0) as green, and (1.0, 1.0) as blue circles. (b) Monte Carlo simulation for the spin-polarized magnetic focusing for (i) both QPCs are spin-resolved, with (Ne, Nc) = (0.5, 0.5), (ii) emitter QPC is only spin polarized, with (Ne, Nc) = (0.5, 1.0), and (iii) both QPCs are not spin-resolved, with (Ne, Nc) = (1.0, 1.0). (c) Time evolution of spin vector components (Sx(t), Sy(t), Sz(t)) at the first focusing peak. Spin components Sx, Sy, and Sz are calculated during the focusing time (2.5 ps) from emitter QPC to collector QPC. Dotted lines correspond to the trajectory of the adiabatic limit where the spin precession frequency is much faster than the cyclotron frequency. (d) Spatial evolution of spin orientation calculated in (c) along the semicircular orbital trajectory.
