We have studied the effects of spin-orbit coupling in doped semiconductor quantum wells (GaAs and CdMnTe) with electronic Raman scattering. In these structures exist intrinsic magnetic fields (Dresselhaus and Rashba). These fields offer attractive means to manipulate the electron spin, but contribute also to spin relaxation, through their dependence on the electronic wavevector (D'yakonov-Perel' mechanism). We show that for the collective spin modes of quantum wells, the destructive D'yakonov-Perel' scenario is transformed into a constructive scenario: Coulombic interactions lead to the emergence of a collective spin-orbit field, proportional to the excitation wavector, and several times enhanced with respect to the single-particle spin-orb...
