Abstract

Complex variations of a magnetoresistance oscillation pattern with a tilted magnetic field angle are found in a n-In0.2Ga0.8As/GaAs double quantum well. These variations reflect the nontrivial behavior of gaps in the calculated magnetic level patterns. Fourier spectra of oscillations in tilted fields also exhibit a complex structure, and the sum of frequencies of peaks is not constant. It is assumed that this is associated with the magnetic breakdown effect.
