Abstract

It is shown that capacitance spectroscopy can be used to investigate the spin polarization of two-dimensional electronic systems (2DESs). We employed this method to investigate the spin polarization of 2DESs in a GaAs/AlGaAs heterojunction for filling factors of the magnetic-quantization levels 0.28<ν<0.9. It is proved that in the presence of states of the fractional quantum Hall effect with νf=1/3 and 2/3 the ground state of a 2DES with ν>2/3 is incompletely spin-polarized.
