Spin dependent 2D electron scattering by nanomagnets

► The artificial namomagnets with gigantic magnetic moments strongly interact with spins of electrons. ► In 2D geometry this interaction controls the electron-nanomagnet scattering. ► The scattering amplitudes are two-component spinors. ► The scattering lengths depend on orientation of magnetic moment of the nanomagnet, the electron spin, and the scattering angle. ► This dependence can be used for controlling the spin currents.
