Abstract

The charge-density magnetoexcitations in the bilayer electron system have been studied by means of inelastic light-scattering spectroscopy. Two principal magnetoplasma excitations of different symmetry, acoustical and optical magnetoplasmons, were observed. These principal excitations couple with in-phase and out-of-phase Bernstein modes at nonzero in-plane momentum through the many-body Coulomb interaction. Detailed measurements of the coupled mode energies were performed and compared with theoretical calculations.
