Abstract

The magnetoresistance of an electron system in a selectively doped, wide quantum well of AlxGa1-xAs is studied with the magnetic field (B) tilted slightly away from the sample plane. We observe a dramatic manifestation of the subband-Landau-level coupling. At low B, we observe magnetoresistance oscillations which are not periodic in 1/B, and are related to the magnetic depopulation of the hybrid (electric-magnetic) subbands. At higher fields, Shubnikov de Haas like oscillations (periodic in 1/B) are observed as the Fermi level crosses the quantized energy levels associated with the lowest hybrid subband.
