Abstract—The theory of the Shubnikov–de Haas effect is generalized to the case of two-dimensional systems
with several occupied size-quantization subbands. Possible interlevel scattering is taken into account. It is shown
that the relative amplitudes of the Shubnikov–de Haas oscillations are determined not only by the occupancy of
the subbands but also by the intensity of intersubband transitions. © 2000 MAIK “Nauka/Interperiodica”.
