Band structure of [100] (CdTe)m/(Cd1-xMnxTe)n superlattices is calculated theoretically in dependence of semiconductor CdTe and Cd1-xMnxTe layers width and magnetic component concentration. Calculations are carried out within semiempirical tight-binding method, which includes s-, p-orbitals of each atom and cation d-orbitals. Mn 3d-states contribution to the formation of the superlattice energy spectrum is analyzed. It is shown that a superlattice on the base of diluted magnetic semiconductor Cd1-xMnxTe with small width of CdTe layers is a semiconductor materials with the similar magnetic properties but with more complicated dependence of crystal forbidden band gap on magnetic component concentration.
