Abstract
GaAs/AlGaAs heterojunctions were used to study the fractional quantum Hall effect and the exchange enhancement of the spin splitting in a tilted magnetic field. The activation energies for the Landau level filling factor μ = 2 3 increased by tilting the field, whereas the activation energy for v = 1 3 decreased. The activation energy for the filling factor v =1, which corresponds to the spin splitting of the lowest Landau level, showed a strong increase at small tilt angles and a smaller increase at high tilt angles. The enhanced g-factor was also seen in a direct measurement of the splitting at high tilt angles by the coincidence method.
