Abstract
Magnetoexciton bands of quasiperiodic superlattices with the magnetic field along the growth axis are investigated theoretically. Each optically active exciton state of an isolated well broadens into a band studded with many gaps. The computed magnetooptical spectra of each band consist of several excitonic peaks originating from the critical and surface states. These peaks should be observable in Fibonacci superlattices.
