The Ginzburg--Landau equations derived in this paper for doped superconducting superstructures containing both normal and magnetic impurities are used to investigate critical magnetic fields. In the temperature range where the superstructure period a is much shorter than the coherence length xi(T), the angular dependence of H/sub c/2 has been found to be universal and to depend on the anisotropy coefficient ..cap alpha.. only. Effects of disorder (i.e., deviations of the superstructure potential from periodicity) on the results obtained are discussed in terms of localized states.
