Magnetic Switching of Spin-Scattering Centers in Dresselhaus [110] Circuits

Spin carriers subject to Dresselhaus [110] (D110) spin -orbit coupling (SOC) gather null spin phases in closed circuits, contrary to usual Rashba and Dresselhaus [001] SOC. We show that D110 spin phases can be activated in square circuits by introducing an in -plane Zeeman field, where localized field inhomogeneities act as effective spin -scattering centers. Our simulations show rich interference patterns in the quantum conductance, which work as maps for a geometric classification of the propagating spin states. We also find that disorder facilitates low -field implementations.
