Notes:
Magnetoabsorption and magnetophotoluminescence spectra of type-II (GaAs)m/(AlAs)n superlattices with (m,n)=(3,5) and (5,6) have been measured in pulsed high magnetic fields up to about 40 T. Large dependence of the diamagnetic shift of the excitons on the field direction was observed in magneto-photoluminescence spectra, strongly suggesting XZ character of the conduction band minima for these values of m and n. Oscillatory structures related to the higher lying Γ-like conduction band are also resolved.
