In the presence of a weak electromagnetic perturbation, it is shown that a bilayer quasi-two-dimensional spin polarized system exhibits coupled in-phase and out-of-phase charge and spin density resonant excitations. These modes occur when either the self-consistent magnetization or Coulomb interacti
