Magnetotransport in 2D electron systems with a Rashba spin-orbit   interaction
  The beating pattern of Shubnikov-de Haas oscillations in 2D electron system in the presence of a Rashba zero-field spin splitting is reproduced. It is shown, taking into account the Zeeman splitting, that the explicit formulae for the node position well describes the experimental data. The spin-orbit interaction strength obtained is found to be magnetic field independent in an agreement with the basic assumptions of the Rashba model.
