Abstract

We present magneto-optical evidence for the formation of a magnetic-field-induced spin superlattice in modulated ZnSe/Zn1-xMnxSe structures. In the samples studied, the offsets in both the conduction band and the valence band are very small at zero magnetic field. When a magnetic field is applied, the large Zeeman splitting of the Zn1-xMnxSe band edges overcomes the zero-field offsets and results in the formation of a spin superlattice in which spin states of both electrons and holes are spatially and periodically separated.
