Zusammenfassung

We report on an inelastic light scattering study in the two-dimensional electron system at filling factor ν=1. The energy and the inelastic cross section of the cyclotron spin-flip mode are analyzed. The exchange enhanced electronic g factor in the quantum Hall ferromagnet is measured. In addition to the magnetoplasmon and cyclotron spin-flip modes, inelastic scattering lines associated with ...
