Up to 12 beating nodes have been observed at magnetic fields between 0.9 and 6T. Zero-magnetic-field spin-orbit splitting energies up to 30meV have been directly determined from the node positions as well as from the intersection of self-consistently calculated Landau levels. These values, which exceed the thermal broadening of Landau levels, kBT, at room temperature, are in good agreement with Rashba spin-orbit splitting energies calculated by means of an 8×8k∙p Kane model. The experimental Shubnikov–de Haas oscillations are also in good agreement with numerical simulations based on this model.
