Calculation of the unstrained band offsets between conventional zinc-blende II-VI superlattices (ZnS/ZnSe/ZnTe), or between magnetic II-VI superlattices (MnS/MnSe/MnTe) or combinations thereof (MnX/ZnX) show that (i) the range of offsets spanned by different magnetic II-VI superlattices is compressed by a factor of 2 relative to the range of offsets spanned by conventional II-VI superlattices, (ii) the distance between the Mn d band and the valence-band maximum in MnX depends weakly on X, while in conventional II-VI superlattices (e.g., Zn $3d$ in ZnX) there is a wider spread, and (iii) unlike the case for conventional commonanion II-VI superlattices, the mixed offset ΔEV(ZnX/MnX) depends strongly on X. We show that all three effects have a simple and common physical origin.
