| Abstract: | The magnetic field dynamics of intersubband collective excitations in two-dimensional electron systems based on Mg x Zn1-x O/ZnO heterostructures is studied by the Raman scattering method. It is found that, upon the change in the spin polarization under conditions of the transition from the filling factor ν = 2 to ν = 1, the energy of the intersubband magnetoplasmon changes considerably. The performed theoretical analysis shows that this effect is attributed to the concomitant change in the exchange interaction in the excitation energy. |
