| dc.description | The activation gap $Δ$ of the fractional quantum Hall states at constant fillings $ν=2/3$ and 2/5 has been measured as a function of the perpendicular magnetic field $B$. A linear dependence of $Δ$ on $B$ is observed while approaching the spin polarization transition. This feature allows a direct measurement of the $g$-factor of composite fermions which appears to be heavily renormalized by interactions and strongly sensitive to the electronic filling factor. | |
