Abstract
We present spin-resolved measurements of the local density of states in Si-doped GaAs. Both spin components exhibit strong mesoscopic fluctuations. In the regime of the lowest Landau band, the main features of the spin-up and spin-down components of the local density of states are found to be identical apart from Zeeman splitting. Based on this observation, we introduce a new method to measure the g-factor in a material where macroscopic methods are severely restricted by disorder. Differences between the spin-up and spin-down components are discussed in terms of spin relaxation due to spin-orbit coupling.
