dc.description.abstract The activation gap δ of the fractional quantum Hall states was measured as a function of the perpendicular magnetic field. A linear dependence of δ on magnetic field was observed while approaching the spin-polarization transition. Composite fermions (CF) were introduced via the Chern-Simons gauge transformation on the many-electron wave function. The sharp linear magnetic field scaling of δ while approaching the spin-polarization transition yields a direct measurement of the CF 'g' factor alone. eng
