    Abstract

    We theoretically demonstrate that a rotating electric-field component of circularly polarized microwaves or terahertz light can induce electron-spin polarization within a few picoseconds in a two-dimensional electron system with the Rashba spin-orbit interaction by taking advantage of magnetoelectric coupling. The efficiency turns out to be several orders of magnitude greater than that of conventional methods, indicating high potential of this technique in future spintronics.
