Effect of Spin orbit coupling and magnetic field on the RKKY Interaction in a 2D EG

POSTER

Abstract

The interaction energy for the indirect-exchange or Ruderman-Kittel-Kasuva-Yosida (RKKY) interaction between magnetic spins localized on lattice sites of a 2D electron gas (EG) like in a MOSFET with spin-orbital coupling will be presented using linear response theory involving propagator Green’s functions. The effect due to magnetic field will be investigated taking into account both Landau quantization and the Zeeman term. Both analytical and numerical results will be discussed.
