Abstract :
In this study, the stray field induced by ferromagnetic patterns is used to align spins in flowing electrons. The spin polarized electrons will experience asymmetric scattering due to the strong spin-orbit coupling in InAs based semiconductors, and yield to a transverse voltage even in absence of external field.
