Spin resonance in a quantum wire: Anomalous effects of an applied magnetic field Academic Article

abstract

• We show that in a quantum wire the effective spin-orbit-induced internal magnetic field leads to a narrow spin-flip resonance at low temperatures in the absence of an applied magnetic field. An applied dc magnetic field perpendicular to and small compared with the spin-orbit field enhances the resonance absorption by several orders of magnitude. The component of the applied field parallel to the spin-orbit field separates the resonance frequencies of right and left movers and enables a linearly polarized ac electric field to produce a dynamic magnetization as well as electric and spin currents. 2012 American Physical Society.
