Abstract


  • The gate-controllable Ruderman-Kittel-Kasuya-Yosida RKKY magnetic interaction between the

    magnetic impurities embedded in one- and two-dimensional electron gas in the presence of Rashba

    spin-orbit coupling was analyzed theoretically. By using the eigenfunctions of the single-particle

    Rashba Hamiltonian as the basis of second quantization, we derived the RKKY interaction by fully

    taking into account the spin-orbit interaction. The dependence of the RKKY magnetic interaction on

    the Rashba spin-orbit coupling strength was obtained numerically. Our results clearly indicate that

    the RKKY interaction can be significantly modified by an applied voltage via the Rashba spin-orbit

    coupling.
