Shubnikov–de Haas oscillations are measured in wide parabolic quantum wells with five to eight subbands in a tilted magnetic field. We find two types of oscillations. The oscillations at low magnetic fields are shifted toward higher field with the tilt angle increasing and can be attributed to two-dimensional Landau states. The position of the oscillations(More)
Shubnikov-de Haas oscillations are measured in wide parabolic quantum wells with 2 subbands occupied in tilted magnetic field. Experiments reveal anticrossing of the Landau level (LL) belonging to lowest subband and last LL belonging to the second subband. Such anticrossing occurs due to decrease of the energy of the LL with tilt angle Q: This observation(More)
