Abstract
The interaction coupling of cyclotron transitions with different spin orientation was investigated as a function of density for electron inv ersion layers in GaAs in the magnetic quantum limit. The spatial elect ron distribution strongly influences the coupling of the electrical di pole transitions, resulting in deviations from the interaction strengt h for ideally two-dimensional electrons. At the higher densities the c oupling is essentially reduced due to the finite thickness of the inve rsion layer, whereas at sufficiently low densities the coupling reflec ts the influence of disorder.
