Abstract
In two-dimensional hole systems the anisotropic dispersion E( k) gives rise to a highly anisotropic Zeeman splitting with respect to different orientations of an in-plane magnetic field B relative to the crystal axes. We obtain good, qualitative agreement between theory and experimental data, taken in GaAs 2D hole systems grown on (1 1 3) substrates, showing the anisotropic depopulation of the upper spin subband as a function of in-plane B .
